【Abstract】 The mathematic models are presented to describe the kinematic and dynamic characteristics of kinematic chains and mechanisms by proposing a new topological characteristic matrix LLJM (LoopLinkJointMatrix) and link,joint type coefficients. The interrelationships of topological structure and kinematic behaviors of kinematic chains are revealed. The designer can evaluate and optimize kinematic chains by studying their topological characteristics at conceptual design stage.更多还原
