Suspension
R2026bThe 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.

Featured Examples
Kinematics and Compliance Virtual Test Laboratory Reference Application
Generate optimized suspension parameters for the vehicle dynamics mapped suspension blocks.
Import Data to Independent Suspension K and C Block
Import kinematics and compliance (K and C) test data from AB Dynamics® MAT files, fit suspension parameters, and populate the Independent Suspension - K and C block in a Simulink® model. Use this workflow when you have laboratory K and C test data and want to parameterize a Vehicle Dynamics Blockset™ suspension model without manual data entry.
