主 题:multibody systems redundant constraints joints contact analysis
摘 要:This paper deals with the modeling of a multibody system in which some pairs of bodies are connected by more than one joints with the same kinematic *** such system,the redundant joints must be removed out artificially to ensure the solvable condition of the equations of motion being *** is believed but not obvious that the redundant joints have no effect on the system *** give a strict positive proof of this argument and present a method to avoid the ambiguity in the reaction forces of redundant joints through contact analysis of joints.
