Crank

 

Figure 1  Crank example

 

RecurDyn/Crank consists of system builder, geometries, and connecting elements. The user can create crank system easily using system builder. Geometries such as engine block, crankshaft, conrod, piston pin, piston, flywheel, torsional damper, balancing shaft and EDT can be created. Geometries are connected by connecting elements such as bearing, engine mount, liner connector, gas force, and Balancing Screw Coupler.
After setting up a Pre-Global data and Global data, the user can create components to structure Crank System using two kinds of method. One is System Builder which is a method using Component Builder. In the Component Builder dialog page, the user can create components by selecting the geometries and connecting elements the user needs to create. The other is Manual Builder, which is a method to create components by clicking component icon one by one in RecurDyn/Crank.

 

Step to run Crank System

1.  Define a pre-global data of an engine.

2.  Define a global data of an engine.

3.  Select geometries and connecting elements at Component Builder.

4.  Define values of selected geometries and connecting elements.

5.  Build up an engine model by clicking OK.

6.  Run the simulation.
