An Impact Dynamics Modeling Method with Tangential Impulse in Three-Dimensional Space

Abstract:

This paper studies the impact of two rigid bodies considering tangential friction in three dimensional space. It extends Stronge’s spring-based planar contact structure to three dimensions by introducing three orthogonal virtual springs. Impact analysis is carried out using normal impulse rather than time as the only independent variable, unlike previous work on tangential impulse. This makes the algorithm more compact. At last, collision is governed by a system of differential equations. Modularity of the impact model makes it easy to be integrated into a multi-body system.
