碩士 === 國立臺灣科技大學 === 機械工程系 === 103 === The thesis presents a single-degree-of-freedom spring-based statically balanced mechanism with self-regulator under variable payload. Subject to different payload, the proposed mechanism can automatically adjust the connecting points of the spring without the help of electric motors or manual operation. The presenting design is composed of a statically balanced mechanism and a spring adjusting mechanism. The statically balanced mechanism uses cables to adjust the spring connection points for satisfying the statically balanced condition. The cables are driven by the spring adjusting mechanism. When different payload is applied onto this mechanism, the mechanism can drive the cables to move the spring connecting points to suitable places where the overall potential energy of the mechanism and the payload will remain constant within the workspace of the mechanism. A numerical example is provided to illustrate the design under a payload ranged from 0 to 2 kgw. A computer-aided design model of the design is provided, and a prototype is built up and tested to verify the design. The testing results show that the prototype can reach statically balanced condition under variable payload between θ＝0°~ 45°.
