Mechanical product design is crucial in many engineering field and lots of industries. CAE simulation has been widely applied for predicting virtual product design for a few decades to reduce the cost and shorten the design life cycle. Because of complicated geometry, material/geometrical nonlinearity and complex conditions, it is painful to efficiently and accurately simulate and predict challenging mechanical product designs, especially for those having joint connections or contact interactions. COMSOL® software is known for its powerful Model Builder and complete simulation capabilities. In this paper, COMSOL Multiphysics is applied to predict typical mechanical product designs, where rigid connectors represent joint connections and penalty method executes contact interactions.
