ADVANCES IN DYNAMICS OF HIGH-SPEED MECHANISMS

Dynamics research and control of high-speed mechanisms, which may involve manyfields of developing subjects, are a tough problem. The advances in the fields of flexible multibodydynamics and time-periodic systems, which are the bases of dynamics research in the fields ofhigh-speed mechanisms, are surveyed at first. Then, the state-of-arts of the dynamics research insome typical mechanisms such as linkage mechanisms and cam-follower mechanisms is introducedin detail. The research on the dynamics of mechanisms with clearances is followed with interestand the advances of active vibration control in flexible mechanisms are briefly dealt with. Finally,a number of open problems in the fields concerned are addressed.
