摘要
A kind of 3-RRR parallel robot is described. The dynamics model is analyzed. Experiment is performed to characterize the self-excited vibration of a 3-RRR parallel robot. The measured data is analyzed to describe the dynamics characteristics of the parallel robot system. It is found that the hysteresis is obviously related to the displacements and driving torques of the corresponding actuated joints. The hysteresis, which is caused by the friction and backlash of the speed reducer gear existed in the mechanism, could describe the positioning nonlinearity. © Springer International Publishing Switzerland 2014.
