The recruiting phase to join the Dynamis PRC team in the 2021/2022 season has just begun.

As Dynamis PRC continuously strives to look for the most talented students at our university, we are ready to welcome those new members, whose passion for this sport stimulates them to get involved and commit to achieving ambitious goals!

If we were able to capture your attention and enhance your enthusiasm, we strongly suggest you keep reading the following paragraphs. This will help you to know what it means to be a member of Dynamis PRC, how to apply to it and what jobs and challenges the various departments of the team face on a daily basis.

What awaits you?

Being part of the Dynamis PRC team not only implicates confronting yourself with a severely different reality than the one you are typically used to as a student, but also entering a world where you are given the possibility to put into practice the knowledge acquired during your studies as well as the different skills that are difficult to practice in a common university context.

In our team you will be working on an important project such as a racing car that will inevitably generate various real-life problems which you will need to solve both in our workshop units and from home. In addition to that you will be given the opportunity to perform exclusive duties that you would hardly be able to do elsewhere, such as track tests assistance or competing in races held all over Europe.

Furthermore, you will have the chance to be part of a group of extraordinary, highly motivated and experienced people, with whom you will be able to share everything related to the life within the team.

Once entered the team, we will proceed by informing you about the different software employed as well as the tools and skills necessary to work independently on the design and production of the future prototype. On the other side we expect you to show great desire to learn and a lot of commitment in tackling the tasks that will be assigned to you.

Ultimately, you will be given the unique possibility to approach the business world by doing a lot of practice in building something concrete of which you will be able to see the results month after month and also by confronting yourself with our sponsors and relevant companies operating in the automotive sector and elsewhere.

How do you enter the team?

Show us what makes you a valid added resource to the team by taking part to our entry test!

This test will be held through the use of the platforms Microsoft Teams and Microsoft Forms;

These tasks concern the subjects of interest to all departments of the team.
  4. Sezione D: this part is specifically related to the chosen department/s and composed by two or three open questions. You could be faced with practical problems related to daily occurrences within the department itself as we want to see how you manage those critical situations and to which conclusions you arrive at!

The total amount of time for the test is 1.45/2.00 hours.

This recruiting session is dedicated exclusively to those who aim to cover technical roles within the team and therefore for the departments: Aerodynamics, Suspension & Drivetrain, Chassis, Vehicle Dynamics, Driver Interfaces, Cooling System, Driverless and Electronics and Powertrain.
In relation to the Business & Marketing sector and the logistic figure the recruiting will be held approximately between September and October 2021.

Team Departments

The aerodynamics department deals with designing, producing and validating the whole aero package of the prototype. The designing phase consists of drawing, with the help of CAD software, all the aerodynamic components of the vehicle with a great focus on increasing performance and their later testing through CFD simulations in which we set all the relevant parameters and solve any geometrical conflicts. We also proceed to a critical analysis of the results. Simulations are an essential part of the department’s work and we are always striding to achieve the most efficient and advanced techniques. Once a nearly definitive geometry has been defined we work with the Chassis department to study the best lamination sequences and we design the necessary moulds and models required for production. The production process varies depending on the component. Sometimes building just the mould can be enough whereas sometimes it might be required to also build a model of the component, on which to laminate the mould. We can either do a wet layup (in our workshop) or a dry layup (at our sponsors).  Once the lamination has been completed we finish and assemble the aero package. On-track validation is carried on using load cells, pitot tubes and flow-wiz. The acquired data is then analysed to understand the effectiveness of the component’s design and to identify the aspect we want to improve.

The main focus of the Chassis Department is to design and build the carbon fibre monocoque along with all the support require by all the components connect with the chassis with the goal of obtaining a high torsional stiffness whilst guaranteeing a low weight, allowing for minimal compliances and great reliability. At the same time we design driver’s safety feature, especially crumple zones and firewalls. The department also designs the TS accumulator container and inverter container. The structures have to be strong, stiff and light whilst being in full compliance with all rules. A great area of interest for the chassis department is the research in the field of material engineering as we always strive to achieve the best performances. We mainly use composites but also have components made of metals and polymers. After an initial phase where we critically analyse the problems ad find possible weak points we start an iterative CAD and FEA designing phase to optimize the components. We produce most of our parts at our sponsors’ working closely alongside the Aerodynamics department to find the best solutions to laminate the components made of composites.  Last but not least we validate our components during track days.

This department designs and builds the entire cooling system of our single seater, focusing especially on weight, performance and reliability. Our work is mostly concerned with the accumulator container, inverter and radiator. The accumulator container is designed taking into consideration air vents, disposition of the batteries, outlet ducts and fan choice. Once the electrical motors have been chosen we study and develop the cooling jackets mounted directly onto the motors’ cases, optimizing both the internal and external geometry, flow rate and production process. As far as the inverter is concerned we define the coolant’s path through the cooling plate, to which most components are in contact with, to increase efficiency. In order to dissipate the heat generated by the motors and the inverter a radiator must be designed to achieved the best working temperatures. Size, position and fan choice are all crucial to guarantee the desired flow rate and minimize the impact on the aerodynamics of the car. Each component must be integrated with the rest of the vehicle to obtain stability and lightness. A great example is the fans’ support, designed with the help of a topological optimization. The sizing of the entire cooling system is support by a predictive Matlab and Simulink model developed by the Vehicle Dynamics and Electronics & Powertrain departments which helps estimate the heat generated and the temperature in the system. Most of our department’s work is based around both fluid dynamics and thermal simulations implement exact models for our components. The production phase is carried out both in our workshop and at our sponsors’.

The Driver Interfaces department designs and builds all the car’s systems that come in direct contact with the drivers such as the steering systems, braking system, pedal box and seat. The goal is to obtain systems with great performance minimizing weight whilst maintaining high rigidity and high ergonomic standards. Structural designing includes the use of Finite Element Analysis and topological Analysis for more canon components, whereas others might also need thermal and CFD analysis. Having many carbon fibre parts we also need peculiar ergonomic studies and FEA targeted at optimizing the lamination. The department has many interactions with Suspension & Drivetrain to design the motor wheel, Electronics and Powertrain to design the steering wheel and some sensors and with Driverless to study braking and steering systems for next year’s autonomous vehicle. Our components are mostly made by metal (via milling, turning and 3D printing) and carbon fibre composites obtained by lamination. During track days we collaborate with Vehicle Dynamics to regulate the setup according to the conditions and we also do some maintenance on our parts.

The Driverless department designs and builds the autonomous driving system for the next prototype. Our work covers both software development of all the moduls and algorithms needed to creat a fully autonomous system and the hardware development of all the components required to physically operate the car and the electronic boards required for controlling the vehicle. As far as the software development is concerned we elaborate data acquired from sensors which use machine learning to precisely determine the position of everything that surrounds the car. Starting from the data the optimal trajectory is calculated and optimized. All the control algorithms are needed to determine the correct input values to be given to each physical actuator to best follow the ideal trajectory. Hardwarewise steering wheel actuator and emergency braking are developed alongside the Driver Interfaces department.

Electronics & Powertrain develops and actualize all the control and power supply electronics of the prototype. We develop printed circuits boards and their software, integrating every single module in the vehicle’s electrical system. We also design and build the battery accumulator, develop the motors’ control and do the car’s wiring. The software we develop ourselves are mostly coded in C-language with the use of a real time operating system. Those developed in Matlab/Simulink use a model-based approach. The department also deals with data acquisition and processing coming from the real time sensors mounted on the prototype to increase performance and reliability. A fully in-house build telemetry system allows us to monitor many vehicle parameters in real time allowing us to check, both in a test session and during a race, to check that everything is ok. Our workflow starts with an initial phase where we research and design both circuits’ schematics and CAD models. Our boards are mostly built at our sponsors’ but sometimes we need to solder some components ourselves. We than test and debug our software. As far as accumulator, inverter and engines we are concerned the assembly and validation through thorough testing.

The Suspension & Drivetrain Department designs and build the suspension system and motor-wheels. The main design goals are to reduce the overall dimensions and masses whilst increasing rigidity. We develop our own optimization algorithms to pursue these goals and the final solutions are then validated via FEA, vibrational analysis, fatigue analysis and experimental tests to make sure each component suits its prerogatives. In addition to the design to also develop various models to predict the car’s behaviour in order to estimate the structural loads on the components. Furthermore each components is part of the suspension system’s model in order to understand its dynamic behaviour. Last year we also started to implement thermal, tribological and fluid dynamic models of the gearbox to monitor temperatures, strains and efficiency of the entire system. We produce our components in our workshop and at our sponsors’. Last but not least during tests and races we work in close contact with the car, adjusting the setup and doing the necessary maintenance.

The Vehicle Dynamics department’s main goal the maximise the car’s performance studying and designing various parts. The most important component is the tire, the development of which is done thank to a collaboration with Pirelli started in 2013. Understanding how to make the most out of the tire is the starting point of the design of the entire vehicle and the key to maximize performance. To achieve this we use and develop many models and collect and analyse a great deal of data during track tests in order to estimate the simulations’ accuracy and to properly choose setup parameters. Once the tires’ properties are known we determine the vehicle fundamental properties for the car’s dynamic behaviour such as wheelbase, track and mass distribution, working alongside other departments. The suspensions’ design includes the kinematic analysis, elastic scheme and sizing of all the required stiffnesses and damping. Of great importance is the designing of the torque vectoring with the Electronics and Powertrain department. This algorithm allows us the manage each of the four electric motor’s torque independently. On track we validate our models and define the single seater suspension setup. We also develop a race strategy analysing the data coming from the various sensors mounted on the car and gathering the drivers’ feedback.
