Lumped Model of a Vehicle Suspension System

Application ID: 55751

In this example, a lumped model of a vehicle suspension system having 11 degrees of freedom is analyzed. The Mass, Spring, and Damper nodes of the Lumped Mechanical System interface are used to model the wheels, including suspension system as well as the seats with a passenger. The vehicle body, having 3 degrees of freedom, is modeled as a rigid body in the Multibody Dynamics interface. The External Source node of the Lumped Mechanical System interface is used to connect the MBD model of the vehicle body to the lumped model of the rest of the system.

A transient analysis is performed to compute the vehicle motion as well as the seat vibration levels for a given road profile.

This model example illustrates applications of this type that would nominally be built using the following products:
