Abstract

Abstract

Impact dynamics of multi-rigid-body systems with joint friction was considered. Based on traditional approximate assumption dealing with impact problem, a general numerical method called sliding state stepping algorithm was introduced. This method can avoid the difficulties in solving di-f ferential equations with variable scale and the result can avoid the energy inconsistency before and a-f ter impact due to considering the complex of the tangential sliding mode. An example was given to describe the concrete details dealing with these difficulties.
