Comparing Truck Seat Suspension Dampening Designs

Modeling and simulation can be used to predict the effects of replacing one component in a system with another. In this model an active damper is considered as a replacement for a simple passive damper in the driver's seat of a heavy truck.

To run this example, you'll need

The latest versions of SystemModeler and Mathematica.

Create Hybrid Models

Replace a simple passive damper with a hybrid active damper.

Numerical Experimentation

Compare the behavior of different real and idealized system designs under identical input conditions.

Semi-active damper component that applies velocity-dependent damping in one direction of motion
Semi-active damping performs better than passive damping across a range of frequencies.

Compare Designs

Test an alternative design by creating a drop-in replacement component.

Analysis & Custom Visualization

Visualize amplitude frequency response curves by computing the envelope of the response of each system to the chirp input signal.
