| Summary: | 碩士 === 國立成功大學 === 機械工程學系 === 89 === This works targets on a four-bar slider-crank mechanism. The input of this mechanism is the output of a differential mechanism with two degrees of freedom. And, its inputs are a constant speed motor and a variable speed servomotor. The purposes are to avoid the dimensions of the mechanism must change when the required output motion is different for the designs with constant speed motors, and to avoid the use servomotors with big power. The approach can reduce the size of the servomotor power requirements by optimal the speed of constant speed motor. This work designs five types slider-output motion, and compare the dynamic of the design with only one servomotor driving and the design with the combination of a constant motor and a servomotor. The results show that the constant motor provides the most power, and the servomotor controls the variation of the speed. This proves that the proposed design is feasible.
