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.

Another free one and quite successful is Wishbone. First; I want to tell you a tiny little thing I really like one quote or an OptimumG motto that says “Knowledge shared; Is knowledge squared”. And start sketching on the front view geometry by drawing lines to express your wishbones and your unsprung mass and then move to the side view About your topic it had been discussed quite alot, But I’m going to share what I got anyway.

Sorry for any typing mistakes. Thirldy; If you want to start your design process, Then start by visualizing a 3D model of any type of suspension you want What are the functional requirements, for the suspension sub-system, these should emerge from the functional requirement of the car. Or find the yaw moment when both external tires are at peak for different radius. Work well on the compromises Remember that the tires are the only contact you have between the sprung mass and the ground.

I’d start by analyzing and understanding a few existing suspensions. The time now is Why were certain concepts used and others abandoned? Introduce yourself properly; namecountry, team You can’t truly design something if you can’t perform an analysis on it.


It’s skipped forward to the final 5. Milliken Research Associates, Inc.

Suspension Design Step by Step Process

One thing that can be noticed is actually how bumpy the track 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.

Use the Bicycle model first for practice, then build to a Four Wheel 2D model. Suspension Design Step by Step Process. Then, build, race, win. Don’t stop studying; Once you start design; Study more not less! Study the pneumatic tires very well User Name Remember Me?

You can’t wait to perfect your knowledge and analysis–you’d never design anything! After this iteration, how can these ideas you’ve formed achieve your high level goals? The more times you go around the cycle the more you learn, the better your analysis gets and the more engineering you have in your design. If you could give me a list from start to finish 1,2,3,etc in terms of calculations and parameters to sispension, that would be great.

There is a knowledge-analysis-design- evaluate cycle With this you can use your tire model to obtain forces on the car, these forces will make you able to calculate load transfers, then re-calculate the tire forces, and iterate till you converge.

Read and understand about the bicycle model, the understand the behaviour of the model and the tire. 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 might want to use the Stackpole Engineering Pacejka model from TTC Round 3, it might not be your tire, but it will give you a good indication of the common behavior of a fsae tire.


Analyze handling of the car for different parameters and choose system parameters. Prior art, read on suspension design in RCVD for example. These specifications should be written in a table for fast reference. One of the best softwares out there is OptimumK however it is not for free. Who is using what, what has been used before? Is there something that can suspejsion innovative to the design? Vehicles without suspension have won, and they can be fast, as long as fssae proper adjustments are left open for balance.

It should be very helpful too. You will have to make basic assumptions to estimate the values. Be patient enough; The whole process might take up to a month of hard working. I remember watching a video where Fsse. Know why before knowing how!!

The suspension must permit vertical movement between the suspended mass relative to the tires. Results 1 to 10 of Hello Benn, First warm greetings and afterward; I’m a beginner too so don’t take this as an expert talk
