Abstract

In this paper computer implementation of automated simulation of rigid bodies in collision is presented. It can be used for automatic simulation of unconstrained and/or constrained mechanical systems. The key tasks include feature extraction, collision detection, constraint identification, collision response, and simulation. Feature extraction includes volumetric feature extraction such as mass, volume, density and moment of inertia, and planar geometric feature extraction like the faces, edges, vertices and their inter-relationships. Collision detection is a kinematic problem involving the positional relationships of rigid bodies in space, while collision response is a dynamic problem involving the prediction of rigid body behavior according to physical laws. Case studies are used to explain the behavior of a typical system comprising of two rigid bodies to explain the underlying principles.
