近年來，隨著休閒運動風氣的盛行，登山自行車已成為休
閒運動器材市場上最受矚目的產品之一，且基於更高標準
的操控性與舒適性的要求，性能優異的後懸吊機構更是登
山自行車必備的關鍵性組件之一。本研究之目的在於應用
工程設計方法的概念，提出一套登山自行車後懸吊機構系
統之設計理論。首先調查登山自行車後懸吊機構系統之基
本需求，進而決定本研究的設計目標，以建立登山自行車
後懸吊機構系統之性能規格書;其次進行後懸吊機構的運
動設計，以電腦輔助試誤法程式做為合成的工具，合成出
滿足性能需求的後懸吊機構尺寸;最後利用拓樸學理論合
成登山自行車之車架構造，並開發系統化程序進行登山自
行車後懸吊機構系統的具體化設計。

With the prevalence of leisure sport, riding
mountain bikes becomes an enormous vogue today.
The mountain bikes undoubtedly have become one of
the most popular products in the leisure sport
market. Based on its superior standard of
operating quality and the demand of
comfortableness, the requirement of the
outstanding rear suspension mechanism of mountain
bikes is one of the crucial components in the
design procedure. The purpose of this work is to
provide a design procedure of the system of rear
suspension mechanisms of mountain bikes by using
the concept of engineering design method. First,
to investigate the essential requirements of the
system of rear suspension mechanisms of mountain
bikes is started. Then the design targets of this
research are decided further in order to
establish the requirement book for the system of
rear suspension mechanisms of mountain bikes.
Second, the kinematic design of rear suspension
mechanisms is proceeding. Computer Aided Tried
and Error program is utilized for synthesizing
the dimensions of rear suspension mechanisms to
meet the requirement of functions. Finally,
topology theory is applied to synthesize the
frames of mountain bikes. Furthermore, the
systematic design procedure is developed to
perform the embodiment design of the system of
rear suspension mechanisms of mountain bikes.
