OS-T: 1900 Dynamic Analysis of a Three-body Model
In this tutorial, dynamic analysis on a simple three rigid bodies model is performed using
OptiStruct. The force of gravity acts along the global Y axis, and the system has one degree of
freedom.节选段落二：
The model has three components and a few free nodes that
will be used to create bodies and joints for the MBD model.
Setting Up the Model
Creating PRBodies
PRBODY is the Rigid Body Definition for Multi-body Simulation.节选段落三：
In the Model Browser, right-click and select Create > (and then) Load Step from the context menu.
A default load step displays in the Entity Editor.
2. For Name, enter Dynamic .
3. Set Analysis type to Multi-body dynamics.
4. Define MLOAD.
a. For MLOAD, click Unspecified > (and then) Loadcol.
