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:Multibody Dynamics Module
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
