Hi,
I want to replicate some ANSYS model in HyperMesh. The model contains a hole where a bearing load is applied. In ANSYS software that load is easily applied with a dedicated command. However, I cannot replicate this in HyperMesh.
Bearing loads are applied in the half-surface of a cylinder with a sinusoidal distribution as in this image.
I found this .tcl script (Bearing Load Creation — Altair Community) where a bearing load is created, but results do not match ANSYS ones. I created a benchmark model in which the bottom surface is a fixed support and a unique bearing load is applied on the hole inner surface with +Z direction. In the attached images the results can be observed. A 38% missmatch is found in stresses, mostly localized in a stress concentrator in the hole. The stress distribution in the component is quite similar
I believe the differences come from the direction of the applied loads in each node. In ANSYS they are applied all in the same direction (image a) whereas in the HM script this direction changes (image b). However I am not sure about this.
I would appreciate some advice for creating bearing loads in HyperMesh or any comment about it.
Cheers,
Alfonso
