RBE3 elements and boundary conditions

Recommended Posts

Good afternoon,


I am simulating a chassis structure, and I want to simulate the posibility that extreme supports can rotate (there is no restriction from wheels, as I send attached the picture. I am thinking into define a node, connect it with the two supports from my chassis, and restrict the dof of the node (X and Y displacements and X and Y rotations in one side, and Y displacements and X and Y rotations on the other side). How can I do that in Simlab? Thanks in advance.

Note: X and Y are included on the plane of the drawing.

Hello JJJ


You can connect the supports in the chassis to the defined node using RBE from Analysis > Loads & Constraints > Connectors > Manual RBE

For restricting the DOF's of the Independent node of the created RBE's, apply Property from Analysis > Property. 


Select the RBE's from the Model browser. Set the Entity as RigidBar Type as Rbe2. Set the DOF of the Independent node in the DOF tab.
