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

Generally, CVTs are classified as belt-type or toroidal CVTs, and each CVT is basically composed of two parts such as the V-belt and pulley, or friction wheels. In the belt-type CVT, the pulley is driven by a belt placed between two （left and right） circle boards, while in the toroidal CVT, two rollers rotate under the condition being pushed by strong compression power. Since these conventional CVTs use friction force, their energy transfer efficiency might be inferior. Furthermore, although these CVTs require precise structures and processing, they make noise, and are not durable. Consequently, we propose a new structural CVT in this paper.展开更多
