Parttime – Vehicle Dynamics

As a Vehicle Dynamics engineer, you will be responsible for all aspects regarding the handling of the vehicle. This consists of designing the suspension and steering system, determining spring rates, choosing a good set-up, all while ensuring that the design is rule-compliant.

Ideal profile:

Knowledge

Basic knowledge of vehicle dynamics (control theory, wheel angles, steering and suspension geometry)

Soft skills

Teamwork, communicative, eye for detail

Software

Siemens NX, Matlab

What are the tasks:

In a race car the only contact between the ground and the car are the 4 tyres, and therefore it is extremely important to use them optimally to have a competitive race car. We can use tyre data to model the behaviour of tyres in certain cases to find optimal slip angle, camber angle, … and this model will be included in a lap time simulator for the car. As a part timer vehicle dynamics tyre modelling you will be analysing tyre data of the tyres we are using and make a useful model using MATLAB.

Saving weight is imperative to performance, and everywhere is an opportunity to save weight. This includes the brackets that connect the suspension arms to the chassis, as well as the A-arms which connect them to the uprights. The job would be to use the load cases for each suspension arm to topographically optimise each bracket to be as light as possible, while also connecting well to the chassis. These optimised designs would also need to be adapted so they are able to be CNC milled as well.

This position consists in optimizing the code for the algorithm controlling the semi-active suspension. The code was written in MATLAB Simulink and translated to C++. However, we are looking at retranslating the code for clarity and to ensure no errors were made. Your job would be to understand the working principle of the algorithm and translate it using a built in function on Simulink to C++. Also helping out creating a test plan for the algorithm on the 4-poster and on testdays at the race tracks will be one of your tasks.

The team is developing a lap time simulator to simulate the race car driving in different racetracks and conditions. This will be on software like MATLAB or IPGCarMaker. Your job would be to support the Vehicle Dynamics team in the development of this project and validating it with data from test runs of the racecar such that we can make the simulation as close to real life as possible.

FEB are hoping to move away from steering racks bought from suppliers and create their own bespoke steering rack. You would be in charge of designing a completely bespoke steering rack that fits within this year’s monocoque, and can be milled by one of our partners. Together with the Vehicle Dynamics department you would be in charge of determining the steering ratio and dimensions of the steering rack. You would also need to ensure there is as little play and compliance as possible, as well as optimise the design for weight and make it compatible with a driverless steering actuator. Keep in mind that this is a project that would be for th efull year and not align with the design schedule of this year’s car.

Some previous tasks:

Our vehicle is equipped with 80kW (110hp) for a vehicle of roughly 200kg. Without algorithms we are not able to put all this power to the ground and maintain controllability. Your task will be to keep working on our previous algorithms. Make them faster and more accurate while also improving our vehicle simulation model.
You will be in charge of certain testing days where the main focus is testing these algorithms as well as setup testing. As main responsible for this you will have to prepare testing days, go testing, and also process test data and make right decisions.

Since a couple of years research has been done to implement a semi active suspension. Your task will be to optimize this system mechanically. You will improve the pressure drops across the different hydraulic systems while also reducing the weight. You will also be in charge of the testing and validation of this system. This will include 4-poster testing, data collection and processing.
Furthermore, you will choose the suspension layout. This includes finite element simulations on rocker designs and different valve blocks for the semi active suspension.

This consists of designing the suspension and steering system, determining spring rates, choosing a good setup, all while ensuring that the design is rulecompliant. Since a couple of years research has been done to implement a semi active suspension. Your task will be to optimize this system algorithm. You will be in charge of the extension of these algorithms, making them faster and more efficient while also tuning them on a 4 poster.

You will be in charge of designing the steering system of next year’s car. Since we are working to-wards one car that is able to drive autonomously and with a driver, you will design a system where you will include a steering actuator to the steering system. Make sure that these work well together, while keeping an eye on the added weight of the overall system. You will have close contact with the kinematics engineer, to make sure the vehicle keeps having the right characteristics.

As a kinematics engineer within vehicle dynamics, you are the main responsible for the way the wheels move compared to the chassis, as well keeping steering forces low to ensure our driver can drive endurance events. You will have a big influence on the setup of the car where you will simulate different movements like roll, pitch, heave and steering angles to have a closer look at the camber and toe changes. Since our wheel size will be reduced from 13” to 10” to reduce our unsprung mass, this will be challenging to make everything fit in the tight space there is.
