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.

Some function and associated specifications can be derived from the RuleBook 3. Introduce desitn properly; namecountry, team So to choose a tire you need a car, and to make a car you need to choose a tire.

There was a problem providing the content you requested

Know why before knowing how!! Only then will you have to worry with roll centers, roll stiffness, kinematics, motion ratio, dampers and such things. euspension

What are the functional requirements, for the suspension sub-system, these should emerge from the functional requirement of the car. Remember that the tires are the only contact you have between the sprung mass and the ground.


Then go back to your model and edit it again and analyze once more and start iteration. 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. All the fitting is already done and all the equations of the model written down -Write a simple code for the Four Wheel model that is able to calculate the slip angle for a given radius and steering angle, you will have to make assumptions about the slip angle at the rear.

I mean I’m just sharing what I know. I really like one quote or an OptimumG motto that says “Knowledge shared; Is knowledge squared”. User Name Remember Me? Don’t stop studying; Once you start design; Study more not less! All times are GMT You’ll have to loose something in order to win the other. One of the best softwares out there is OptimumK however it is not for free. Now slim the ideas down to a core goal. Work well on the compromises You will have to make basic assumptions to estimate the values.

I’m fairly new to FSAE and suspension design. Milliken Research Associates, Inc. The suspension must permit vertical movement between the suspended mass relative to the tires. Who is using what, what has been used before?


Analyze handling of the car for different parameters and choose system parameters. The time now is Why were certain concepts used and others abandoned?

Suspension Design Step by Step Process

Contact Us Archive Top. It’s skipped forward to the final 5. Results 1 to 10 of These specifications should be written in a table for fast reference.

Secondly; Start by tires Get the basics right first, the details only after. It should be very helpful too. Is there something that can be innovative to the design? The more times you go around the cycle the more you learn, the better your analysis eesign and the more engineering you have in your design.

Do you want to just keep the wheels on xuspension car and complete the laps or do you want a car that is the fastest thing in a corner?
