How to create a revolute joint using RBE2 elements

Recommended Posts

Hello,


 


I am doing analysis of universal joint assembly (Yoke1, Spider, Yoke2). Spider is a cross member which has 4 bars extruded. So there are 4 revolute joints between trunnion and yokes.


Can anybody tell me how to create a revolute joint using RBE2 elements in Radioss Bulk Data?

To create a revolute joint between 1 bar and 1 yoke hole, I applied the following procedure:


1) Create a center node of the spider bar: node A


2) Create a center node of the yoke hole: node B


3) Create a RBE2 (Independent Node: node A, Dependent nodes: all the nodes on the portion of the bar which will be inside the yoke hole.)


4)Create a RBE2 (Independent Node: node B, Dependent nodes: all the nodes on the yoke hole.)


5) Create a local coordinate system having 'x' axis from node A to node B


6) Assign the node A and node B to local coordinate system. (set reference and set distance)


7) Create RBE2 (Independent Node: node A, Dependent nodes: node B; All dof constrained except dof4 (rotation in x axis)


Is this method correct?

Hi Vij,


 


What is the objective?


 


is it a structural analysis or a multi body simulation?


 


If it is a multi body simulation you can use MotionView to model the system.
