Modeling a Radial Cam Based Valve Opening Mechanism
Application ID: 55821
In this example, a spring-loaded valve-opening mechanism consisting of a rocker arm and a radial cam is studied. All of the system components are modeled as rigid and are connected through prismatic, hinge, and slot joints. The cam-follower connection as well as other joint connections are modeled using built-in nodes in the Multibody Dynamics interface.
A transient analysis is performed for various values of valve spring stiffness. The output from the model includes, among many things, the follower velocity, follower acceleration, cam-follower connection force, and the required torque.
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 Tabella delle Funzionalità and make use of a free evaluation license.
