Hi,

We are looking for some clarififcation on rules for headrest placement. We have previously used a design identical to the onshape screenshot below. However when reading the rules we thought that by the letter of the law it may need tubing to brace it? I was wondering if anyone would have any insight as we are really split internally. The gold tubes in this place signify cat A tubing and the pink is cat B&C. Thanks

Hi everybody,

New to the FSAE world, I was told that this is a very good read, does someone has a pdf copy of the book ? Thanks.

Fill this for out by Friday, October 23rd so we can finalized the schedule and all the details
Here is the form link: https://forms.gle/TsqsGtiLCzqs55SJ8

1) What simulations do you run to validate a chassis, and how do you set them up?

I know we need a static torsional stiffness simulation, and I have bending stiffness too. What else is needed (braking, acceleration, and ...)? For each one, how do I apply the loads and constraints? What target values do you aim for?

2)How do you calculate torsional stiffness in this case (the picture below)?

k = T / θ

T = F × Track Width

θ = tan⁻¹(Vertical Displacement / Half Track Width) (same distance case)

What value should I take for the Vertical Displacement?

Hello everyone! I needed help interpreting this new rule added and how we actually need to prove it.
Thank you!

Wanted to share the trailer for Melbourne University Racing (MUR)'s launch night, featuring CGI of our M26 racecar before our car gets revealed on 21/11/26.

We will be competing in the FSAE-A competition this December at The Bend.

Hello Community, we are working on FSAE 2027 for EV Concept

I am using IPG Car control for simulation . it has an interface for implementing HV parametres where i found that it works with 2RC Battery equivalent model , as you know the datasheet of cells provides DC IR which represents the total R and IR AC represents the R0 in this model . how can i get the R1 R2 C1 C2 or any approximate values the time that i get real cells . THE CELLS THAT IM LOKING FOR ARE:

AMPACE JP40

MOLICEL P45B and P50B

BAK 45D

EVE 40PL

if you guys worked before with one of these cells please Help!

Hey everyone!

Our team is currently trying to select dampers for our FSAE car in India, but we're confused about the selection process and the calculations involved. The major issues we are facing are:

• What parameters should we consider when selecting dampers?
• What calculations are required to determine the target damping coefficient and damping ratio?
• How do we match dampers with our spring rates and suspension motion ratios?
• What's the most cost-effective way to source suitable dampers for an FSAE car?

I'd appreciate any resources, calculation sheets, or practical advice from teams that have been through this process.

Thanks!

انا عايز اعمل مشروع تخرج للسنه الأخيرة في هندسة السيارات بس مش عندي فكرة معينه عن المشروع اللي المفروض اعمله في حد عنده افكار انا حاليا في السنه الاخيره في قسم مهندسه السيارات في جامعه بني سويف كنت اريد ان كان عند بعضكم بعض الافكار عن مشاريع التخرج وهكذا بالاضافه نحن سناخذ مشروعا قام به بعض الخريجين وسنقوم بالتعديل عليها هو عباره عن مشروع يعمل عن طريق محرك بنزين يحول الحركه يحرك مولد المولد يولد كهرباء تشحن البطاريات والبطاريات تغذي المحرك الكهربائي والسياره تمشي بالمحرك الكهربائي بالاضافه الى ان السياره بها الطاقه الشمسيه ولا ادري ما الاضافات التي يمكنني ان اضيفها على هذه السياره فان كان عند احدكم علم فل يبلغني

Hi, what is the minimum and maximum battery voltage for emrax 228 MV motor which you have tested?

Does the multimatic roll damper use 2 springs?

Hello. I'm working on a prospective members project for my FSAE team for aero to make a rear wing under the 2026 rules with a certain number of downforce. I started from less than nothing; i bailed out of my ap physics class in high school, but I still learned Aerodynamics from videos and parts of books. I understand it enough to atleast not be that confused, and it took around a couple of months but I did end up figuring it out. Though, I'm realizing a question I never asked was whether I can or even should put the wing on a car. Sure, I made the wing reach the number, but would it work in truth? With me not taking into account either manufacturing or mounting: I can't say no. I'm gonna present tomorrow, and I probably wont be getting in this go around maybe. I'd still want to know where I can learn. I've seen some videos and heard some snippets from the team's discord, but I want to know enough to present something of actual substance next time.

I shared recently but pushed quite a few updates to wrap up the vehicle design flow. Initial setup -> step response analysis -> damper curve fitment -> graphical tool for suspension kinematics in heave, steering, and roll scenarios -> lateral load distribution analysis -> cad export as step or STL. It's all there and more. It's a set of tools I use for work that I'm hoping others can use as well. Feel free to ask any questions.

Greetings everyone, I am Akshat Jain from Spark Racing Team.

Does anyone know the minimum thickness of the Dowsil RTV SE 9168 for which it is V-0. If someone knows please let me know or if anyone uses a different UL94 V-0 rated adhesive which has known minimum thickness please let me know.

My son wants to 3D print F1 rear wings from over the years, to test their downforce in a homemade wind tunnel.

Are there any recommended resources for such information?

Hi everyone,

I am really interested in vehicle dynamics and tyre modelling and would like to pursue a career in driver-in-the-loop (DiL) simulation.

I've been working towards developing my skills in MATLAB, Python, and C++ in more depth, alongside working on a personal project to build my technical knowledge.

For those working in DiL simulation or related fields, what would you recommend focusing on to improve my chances of landing a graduate or entry-level role? Any advice on useful skills, tools, projects, or companies to look into would be greatly appreciated.

Thanks

hi everyone, we've been using the autodesk fusion generative design tool as optimization software for e.g. uprights and rockers for the past few years. during competitions i talked to a team that used nTop - and because ive never heard of it i wanted to take it look if its any good.

does someone perchance have experiences with both softwares and can recommend when to use what? if theres anything missing from my part for your assessment please ask away!

thank you!

We are having problems understanding this particular rule from FSG 2027, is there anyone that could explain it to us? T 3.15.5 The rear impact structure must be positioned such that its diagonal member or equivalent composite structure reacts the loads induced by the IA during vehicle impact, for any position of the minimum IA volume up to 350 mm above the ground.

Hey everyone! I’m from a school with a fairly small FSAE team and this is my first year joining, so I’m still learning a lot about FSAE aswell as racecars and the engineering behind them, in general. This is our first year doing aero on our EV car and I was trying to research ways to manage airflow around the sides of the car. But, I’m getting a little confused because my lead had mentioned side diffusers but most of the reasearch I’m seeing only talks about the rear diffuser or side wings? Are side wings and side diffusers the same thing? How do they look on a FSAE car? Sorry if this is like a stupid question but appreciate any help!

Hey everyone, I made a MATLAB script that maps a track using a .gpx file. It's intended to be used on CarSim (simulation software my team uses), but maybe it'll help out some of you; the output are csv files that contain elevation, curvature, and xyz positions. However, the text is all in portuguese, but all the instructions are in the README and the pdf TRACK_MAPPING_GUIDE. The pipeline is very simple, just: plot a route using plotaroute.com -> download gpx file -> run in matlab

Hey everyone,

We are currently using KBX Vespa brake calipers for our Formula Student/EV prototype vehicle, but we haven't been able to find an official datasheet or detailed technical specifications for them.

We need the specifications for our brake system design and calculations, particularly for brake force and torque calculations and brake system validation.

Hi guys!

We are going to use the CP2 engine for our next car but we have trouble finding the CAD model. If there's someone willing to send us one? We would really appreciate it! ❤️🫂
