What tests should I do for lightening an ev chassis

AI Thread Summary
The discussion focuses on improving the range of an electric vehicle (EV) by lightening its chassis using carbon fiber. The engineering student seeks advice on tests to conduct using Ansys or similar software to ensure the material's safety and determine the appropriate thickness for the chassis. Suggestions include performing a static structural analysis to assess stress and deformation as the chassis thickness is reduced. Participants highlight the advantages of carbon fiber over aluminum and steel, emphasizing its potential for a thinner, lighter design while maintaining strength. Overall, the conversation centers on material testing and design considerations for enhancing EV performance.

TL;DR Summary
Wondering if anyone could help me with what kind of tests I should conduct on Ansys or Matlab to for lightening the weight of the chassis
Hi, I am an engineering student and for my project I have decided to try and improve the range of ev through chassis lightening, the main point I'm focusing on is using a carbon fibre material, so I was just wondering if anyone could tell me what kind of tests I would need to do on Ansys or other softwares to verify if the material was safe to use and how thick the chassis would need to be?
Also, if anyone has any ideas I could incorporate to help improve the range in any other aspects of the cars that would be really helpful!

Thank You!

Welcome to PhysicsForums. :smile:

What size EV? Weight, wheelbase, payload, max speed, etc.? What other carbon fiber chassis designs have you studied?
 
Hi thank you for welcoming me!
In terms of the ev details, its a uni team vehicle that I was going to focus my study on, so I could ask them and get back to you on that information.
The payload is roughly 50 kg driver plus 1.8kg battery section.
Its chassis is made of aluminium, so I was pitching to improve its range through using a carbon fibre material. I am just not sure what kind of tests I should be running on Ansys to comprehensively determine if the how much weight reduction can be achieved.
Only thing I've got right now is maybe do a static structural analysis in which the thickness of the chassis is decreased and see how the stresses and deformation hold up.

Wow, that's a tiny battery! Is there solar cell input power too, or just that small battery?

Can you say what the physical differences are between steel, aluminum and carbon fiber structures like chassis?
 
As far as I am aware I think its only powered by that battery.

I think the real physical difference between the chassis would be that with the stronger material like carbon fibre maybe a thinner chassis could be used to provide the same strength that a steel chassis could, with lower weight.
 

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
