Rolling of a Rigid Wheel
Application ID: 28031
The purpose of this model is to demonstrate pure rolling of a rigid wheel when given an initial forward velocity together with a prescribed lean about this direction.
It is assumed that the the rolling motion of the wheel is not affected by contact such that all three components of the velocity at the point of contact with the ground are zero. In order to achieve this, the velocity constraints are converted into displacement constraints, while the yaw, lean and spin motions of the wheel are defined as three hinges and where their three corresponding massless links are created.
This is easily implemented and performed using the Multibody Dynamics.
This model example illustrates applications of this type that would nominally be built using the following products:
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.
