hinge

Restriction: Available in Nastran, OptiStruct, and Radioss.


Figure 1.

Nastran and OptiStruct

Creates RBE2 elements for the head and the body. The head elements project and connect to the nodes of the adjoining shell elements which form the hole. The connector location can either be on the edge of the hole, center of the hole, midpoint in between the two holes or on the second row of nodes which form the washer layer. The degrees of freedom are constrained in the x, y, z, rot x, rot z for the dependant nodes.

This realization uses the prop_hinge.tcl property script.

Radioss

Creates RBODY elements for the head and SPRING2N body. The rot x degree of freedom is released so that the RBODY can rotate. The head elements project and connect to the nodes of the adjoining shell elements which form the hole. The connector location can either be on the edge of the hole, center of the hole, midpoint in between the two holes or on the second row of nodes which form the washer layer.

This realization uses the prop_radioss_rigidupdate.tcl property script.
