<\/A>Contact Stresses on a Plastic Latch<\/DIV> <\/DIV>
Like trying to loosen the death grip of a black Friday shopper on deeply discounted merchandise, modeling contact can be tricky. Why? Well, for one contact can occur between parts that have rough edges or other awkward geometric characteristics which can hamper convergence. Also, depending on the materials and forces involved, heavy deformations may result that require the deployment of non-linear approaches. Finally, there’s this pesky thing called friction which can change the game if not properly accounted for.
The goal of today’s post is to introduce you to basic, linear surface-to-surface contact in NX Advanced Simulation. Think of this as the basis from which more complex contact phenomena can be pursued. Our example below illustrates contact between caliper and wheel rim in a bicycle brake assembly. You squeeze the brakes, that force gets transmitted via cable to the calipers, which then force the brake pads against the surface of the rim – bringing your two-wheeled personal mobility solution to a gradual halt.
Things to keep in mind – you can manually select source and target contact regions, tweak global contact parameters to influence convergence as necessary, and customize output requests so you get the results you want.
