FSAE SUSPENSION PDF

REQUIREMENT FOR THE DEGREE OF. BACHELOR OF SCIENCE. IN. MECHANICAL ENGINEERING. FSAE Chassis and Suspension. 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. This article deals with design of Formula SAE Suspension by considering various loads and their simulation on each component of the system.

I hope I haven’t said something stupid, if so I duly apologize. I’m fairly new to FSAE and suspension design.

Suspension Design Step by Step Process

Here we can see the relative speed and angular speed that stabilizes after some laps, and the results are considered only for the stabilized part of the steady state corner. An actuator moves the rack causing the front wheels to steer the desired angle.

Then, gsae, race, win. Eigenvectors and eigenfrequencies calculation: What are the specifications associated with your functional requirements.

Comparison of lateral forces and yaw accelerations of the two configurations, soft and then hard:. C2 Hard spring and high damping coefficient: Why were certain concepts used and others abandoned?

After this iteration, how can these ideas you’ve formed achieve your high level goals? The frequencies for the chassis movement have been calculated with the linearization element and are from 3.

I’d start by analyzing and understanding a few existing suspensions. The second part of the simulation is about the skid pad, so the car now is no more constrained over four independent patches but trimmed to let it gain the neutral position on a single road fsze then a torque is applied symmetrically at the two rear wheels following a spline in order to avoid slip on the first phases; the speed is suspebsion stabilized via the very high rolling resistance given to the tire and the steering rack joint driver positions the rack in order to reach the radius of the typical curve suspensjon 18 m.

Willingness to compromise is key to coming up a with a good design, nothing will be perfect.

Then; Put the whole geometry on a kinematics analysis software Fsae is a students engineering competition where student teams from around the world design, build, test, and race a small-scale formula style racing car. It should be very fzae too. God be with you and Good luck with your design.

These specifications should be written in a table for fast reference. You can’t wait to perfect your knowledge and analysis–you’d never design anything! There is a knowledge-analysis-design- evaluate cycle I basically don’t know where to start there is so much information.

The step input has been used to find out the two best configurations amongst the possibilities and to present only the most relevant and useful results for the other inputs. 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.

A kerb or a cone hit at speed is a good approximation of a step input Ramp: 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.

What do you want to achieve? A kerb or a cone hit at speed is a good approximation of a step input.

You can’t truly design something if you can’t perform an analysis on suspenxion. Detail of the CAD front right wheel assembly view from the inside of the car.

Study the pneumatic tires very well Introduce yourself properly; namecountry, team In fact with softer spring on the front the difference is a little higher, but in every skid pad simulation the grip limits of the car are NOT reached, and consequently, as is evident in the yaw acceleration graphs, the car remains neutral. A1 Soft spring and low damping gsae
