Hello forum. I’m fairly new to FSAE and suspension design. One of the overwhelming problems that I’m having is figure out the step by step. Abstract. Design analysis of suspension especially for racecar suspension is very crucial to achieve maximum performance and handling. Suspension design. This article deals with design of Formula SAE Suspension by considering various loads and their simulation on each component of the system.

Suspension Design Step by Step Process. Do you want to just keep the wheels on the car and complete the laps or do you want a car that is the fastest thing in a corner? They have Formula SAE cars and course already modeled into the software.

Not for a particular reason except that there is quite a lot of tutorials on youtube ” Start by darwing two planes; Sjspension view and a side view.

Suspension Design Step by Step Process

The next thing that becomes obvious is the teams that have a good car design, and the cars that dialed in one very in particular if you watch it. Thanks suxpension the information! Another free one and quite successful is Wishbone.

Read and understand about the bicycle model, the understand the behaviour of the model and the tire. Then go back to your model and edit it again and analyze once more and start iteration.


Secondly; There is a “Find” button at the utility bar up at the right just beside the “New” button, So try to search for your topic if it had been discused before so as to save time and effort. Don’t stop studying; Once you start design; Study more not less! Use the Bicycle model first for practice, then build to a Four Wheel 2D model.

You can’t truly design something if you can’t perform an analysis on it. First; I want to tell you a tiny little thing Study the pneumatic tires very well Remember that the tires are the only contact you have between the sprung mass and the ground.

The suspension permits control of the vehicle direction. I’d start by analyzing and understanding a few existing suspensions.

You might not need combined loads at the beginning, but it could be useful for looking at trail-braking and power corner exit and differential selection You suspensoon want to use the Stackpole Engineering Pacejka model from TTC Round 3, it might not be your tire, but desiign will give you a good indication of the common behavior of a fsae tire.

There was a problem providing the content you requested

Then; Put the whole geometry on a kinematics analysis software Understand the basic physics first! The time now is After which; You should be able to transform the whole 2D drawing into 3D you have 2 planes and the third one is the top plane.


You can’t wait to perfect your knowledge and analysis–you’d never design anything!

Sorry for any typing mistakes. What do you want to achieve?

Read as much as you can, follow the groundwork that’s already been laid out from years of people before you. Introduce yourself properly; namecountry, team Who is using what, what has been used before?

All times are GMT I remember watching a video where Mr. Results 1 to 10 of Thirldy; If you want to start your design desin, Then start by visualizing a 3D model of any type of suspension you want So to choose a tire you need a car, and to make a car you need to choose a tire.

Or find the yaw moment when both external tires are at peak for different radius. After this iteration, how can these ideas you’ve formed achieve your high level goals?

The suspension must permit vertical movement between the suspended mass relative suzpension the tires. I have written down one approach, there is no “best” one, but this is systematic, and “relatively” simple since it seems to be your first go at it:
