Our main task is to design and manufacture the monocoque chassis. We are working with different kinds of carbon fiber prepregs, and aluminum honeycombs alongside simulation tools required to design the structure's mechanical performance; all of this of course verified by physical testing.

​

This includes a lot of collaboration between subsystems in working with composite parts, as well as deciding the best ways to attach all other components to the composite structure in locations providing an acceptable compromise between subsystems.

​

The ultimate goal is to build a well-functioning and lightweight car for the season.

​

​

Recruitment good-to-have's but not compulsory! (or skills you will learn)

• Any experience from any kind of composite-related work

• Basic knowledge of strength of materials (chassis)

• Being prepared for a varying workload - sometimes long days, sometimes no workload

• No allergy to epoxy or latex (preferred for your own safety)

The part of our work that is the most visible is the Metropolia Motorsport Team's social media channels. We are the ones translating engineering language into understandable content. 

 

We create content for Facebook, Instagram, Twitter, LinkedIn, and Youtube accounts, where we report other subsystem’s activities and show the insides of the team's life. In addition, we develop team's marketing strategy and materials such as posters, flyers, blogposts, team merch design, etc.

​

We organize events to promote the relationship between the team and the sponsors that cooperate with us. We are also responsible for the deliverables which are agreed with the sponsors in terms of visibility. This is a part of sponsorship agreements as well as promoting our activities to new potential sponsors.

​

The subsystem is in charge of creating the Business Plan Presentation - a part of Static events in summer competitions in Formula Student series.

​

• Experience with graphic design (e.g. printing, logo design, etc.) 

• Experience with tools such as Photoshop, InDesign, Illustrator, etc. 

• Experience with photography and/or videography  

• Creativity, time management skills, openness to learn as you go 

In our subsystem we are focusing on developing the autonomous package for our racecar and creating a virtual model for it. Our goal is too create a fast and reliable DV system.

​

This subsystem is completely new - the upcoming season 2024 will be the first year our team will be researching driverless vehicle design.

​

​

Recruitment good-to-have's but not compulsory! (or skills you will learn)

• Some knowledge of programming languages: Python, C, C++

• OpenCV

• Control & Automation
• Machine learning

We are in charge of building a competitive and reliable suspension for the car. It works in conjunction with the Chassis subsystem to ensure all components are assembled and fit in the most optimal and efficient way.

​

The design, simulation and manufacturing of the suspension geometry and its components are the main functions of the subsystem.

​

The suspension arms are built in carbon fiber, with the goal of creating optimal fastening brackets and inserts for loads. A decoupled suspension system is being built into the car.

​

​

Recruitment good-to-have's but not compulsory! (or skills you will learn)

• Knowledge about steering and suspension components and geometry  

• CAD designing experience  

• CAM and NC-manufacturing knowledge

• Willingness to learn all above  

The subsystem is responsible for delivering the power from the motor to the wheel. Our drivetrain system uses in-wheel motors and 2-stage planetary gear sets, which we manufacture ourselves.

​

Drivetrain members also design the housing of the motors, motor axles, transmission housings and many other parts necessary for the assembly. The focus of Drivetrain is optimizing the gear ratio and making a light and reliable transmission-motor package.

​

Cooling part is in charge of keeping the motors and inverters at operating temperatures. Cooling system uses electric water pumps, radiators and fans to achieve cooling capabilities.

The Brakes subsystem designs, simulates and manufactures the braking system of our car. The main focus is to build a reliable hydraulic braking system that allows the usage of regenerative braking. We size, design, and manufacture the hydraulic box, working on the mechanical side of the regenerative braking feature of the car.

​

Comfort and easy maneuverability is an important factor, as such, we manufacture easily adjustable brakes also taking in mind the leg space and brake feel for the driver. Another feature of the car is that it has a separate pedal box for brake and accelerator which eases the maintenance work.

​

The car has disc brakes, 4 piston calipers in the front and 2 in the back. We laser cut our own brake discs.

​

​

Recruitment good-to-have's but not compulsory! (or skills you will learn)

• Basic knowledge of hydraulic braking system 

• Machining 

• CAD modeling 

• 3D-printing 

This subsystem is the largest one among all. We bring together weirdos who want to use their creativity to make the car go fast with the use of invisible magic. It is quite realistic to call it “The Motorsport Hogwarts”.

 

We are responsible for anything related to electricity around the car, constantly developing features required by the basic functioning of the car, demanded by the rules, ensuring safety and requested by other subsystems. We cooperate with other subsystems to ensure that the electronic and mechanical devices work together efficiently and provide not only the desired outcomes, but also data that will help us improve systems in research and development endeavors of the team.

 

Every year we provide all rounded training for the new subsystem recruits that will allow them to understand the basics of electric theory, big picture of the systems that are being used in our car and entry to the software we work with. 

 

The bulk of the experience in the electric subsystem depends on the skillset and the direction of the desired education of the member. It can consist of tasks like: designing accumulator, designing printed circuit boards (programmable and non-programmable), writing code, creating simulations of the vehicle, designing motor control systems, designing wiring harness, as well as assembling all the systems onto the vehicle. 

 

We are especially happy to let members come up with their ideas on what to develop. You do not like the current steering wheel? Make it functional and look cool with buttons and screen! The brake light looks boring? Design one that exaggerates the shape of the rear! You are a real gamer and need RGB LEDs under the car? DO IT! (But make it detachable, so we don’t have extra mass during the competition races). Be creative and fulfill the needs of your degree while you are having engineering fun.

​

There are several smaller Subsystems under our big subsystem, which are: AMS/Accumulator, Programming, Safety Systems, Wiring Harness and ECU/Sensors/Telemetry.

• HV or LV electronics experience

• Knowledge on microcontrollers (STM)

• Programming (mostly C++)

• Knowledge of PCB design (KiCad)

• Understanding of simulations (LTSpice or Multisim)

• Practical electronics experience

The subsystem is in charge of designing and assembling the aerodynamic package in accordance with the new monocoque chassis of the team.

 

To improve the overall performance of the car, we optimize airflows around the vehicle with new designs using CFD-simulations.

 

Support for the wing structures is designed using FEM analysis to ensure needed durability while having lightest package possible.
