34. Valve

Figure 34.1 Valve example

RecurDyn/Valve consists of system builder and special functions such as:

• Auto Positioning

• Flex Wizard

• MMS3D Import

• Sphere In Arc revolution Contact

The user can create:

• The valve system easily using the system builder

• Components to structure the valve system using the system builder after setting up a Pre-Global data and Global data

Geometries created by system builder are connected by connecting elements such as bearing, contact, and bushing.

Step to Run Valve System

1. Define the Pre- global data of Valve Train

2. Define the global data of Valve Train.

3. Select components and connections in the Component Builder.

4. Define values of selected components and connections.

5. Complete to build up a valve train model.

6. Run the simulation.
