IMPROVING FULL SUSPENSION: SIMULATION CFD CAR WITH SUSPENSION, WITH / WITHOUT DAMPERS: TRACK, BRAKE AND ACCELERATION TEST

In this article, we show the results by CFD Simulation about QUARTER CAR MODEL with Suspension.

In order to improve the suspension behavior, is possible simulate:

• Brake (force in sprung mass).
• Track vibrations.

This model have:

- Sprung mass, with aerodynamic - Down force.

- Unsprung mass, as a car Suspension.

- Between car and suspension, there are spring and damper.

- The unsprung mass, is connect to track, as a tire, with spring and damper.

We have three simulations:

1- Stabilization periode. Necessary before set free the quarter car model.

2- Simulation without dampers, only with springs and masses (gravity is on).

3- Simulation with springs and dampers (gravity is on).

Is very interesting analyze these results and graphics: TRY IT....

Also, is possible to simulate full car, with full suspension (springs, dampers, roll damper, torsion bar, inerters, etc....), and inertia moments, gravity center, tires models, etc....

Finally, is possible also, simulate any vibration in unsprung mass (tires) for simulating any circuit. Amazing that....

THE MAIN GOAL: IMPROVE THE DAMPER AND ALSO, FULL SUSPENSION, AND SO, THE GRIP BETWEEN TRACK AND TIRES.

Thanks a lot.
