碩士 === 崑山科技大學 === 機械工程研究所 === 92 === Traditionally, the main components of rear suspension system of bike are tire, pad, frame, and spring for long years. Recently, alternative rear suspension system components are linkages, suspension strut, and spring. By proper designing the dimensions of the linkage and suspension strut, the rider will long the comfort of bikes. Hence, the purpose of this study is to creative design a new, comfortable, and safe mechanism of rear suspension system of bike. The concept of this study is a rotational damper pair replaces a revolute pair. First, we analyze the topological structure and motion characteristics of existed rear suspension mechanisms. Then, the design criteria of the topological structure are described. Based on the design criteria of topology, the Yan’s methodology of mechanism design is applied to synthesize new rear suspension mechanisms. And, the kinematic and force analysis of these new mechanisms is done well. Finally, a motion simulation of a (6,7) rear suspension mechanism are done well by using the package of Working Model. This research of the provide method can obtain 12 new rear suspension mechanisms with six links.
