Questions regarding NLGEOM analysis

Recommended Posts

Hello,

 

 

 

 

in my analysis of a curve-drive-part is a rotation as SPC, solids for the curve-part (red) and a rigid-spider (blue) to transfer the rotation displacement to the solids.

 

 

I use an NLGEOM-analysis, because i want to simulate the contact between the other parts (not in picture) and the curve-part.

 

 

In this analysis the curve-part shows a strange deformation and the contact force is going very high.

 

 

 

 

 

There is no constraint or force, that explained the deformation.

 

 

 

 

 

Attached filses:

 

 

 

 

 

Topf_Start_1 - front view with a distance measure of 211.666

 

 

Topf_Start_2 - side view

 

 

Topf_End_1 - front with a distance measure of 201.110

 

 

Topf_End_2 - side view

 

 

 

 

 

It is  a model in optistruct, but for the solving is radioss used, because the large sliding contact.

 

 

 

 

 

I want to understand possibly failures in the model.

 

 

 

 

 

greetings
