Application84 Contact Analysis of Mating Bodies

Mating bodies of hook and latch made made of resin are analyzed.

【Analysis Model】
When the hook and latch are in the mating state, all areaa are in contact so as to generate the contact force between the hook and latch.
This means the two bodies are intersecting in an non-stress state.To allow meshing for the intersecting bodies, [Meshing Space] is set.
The analysis is executed in the following steps.
Step 1: A hook body is dead while a latch body is applied load and deformed to the point where they don't intersect.
Step 2: The hook is born. The appliedload on the latch is released gradually.

Displacement diagram, displacement vector, internal stress, and pressure on face are shown.
