Suspension

Independent and solid axle suspensions

The independent and solid axle suspension blocks model the suspension compliance, damping, and geometric effects as functions of the relative positions and velocities of the vehicle and wheel carrier. Using the suspension compliance and damping, the blocks calculate suspension forces on the vehicle and wheels. You can specify:

Multiple axles per vehicle.
Multiple wheels per axle.
Suspension parameters per axle.
An anti-sway bar for independent suspensions.
