This software can display the kinematic characteristics and simulation motion of the mechanism according to different parameters. It also supplies a platform for human-computer interaction. A group of satisfactory parameters were selected by the software. A test bed of EGCR beating-up mechanism was developed according to these parameters. The kinematic performances of the mechanism were verified by high-speed video tape recorder.展开更多
