皮帶與鏈條是目前常用的撓性傳動元件，其中皮帶可以傳遞較高轉速且運轉時產生的噪音相當微小，適合用於汽機車及工業輸送裝置。撓性機構中，傳動皮帶與皮帶輪組成皮帶傳動系統，由馬達帶動主動輪藉著皮帶與皮帶輪間的摩擦力來傳動從動輪，而傳遞動力。一般工業上設計皮帶時，必須先決定馬力、轉速、皮帶輪直徑大小之後，再由傳動帶使用技術手冊中的皮帶馬力轉速規範圖表來決定所使用的皮帶規格，以保持較佳的皮帶設計壽命及傳遞效率。
本論文將針對皮帶與皮帶輪間的運動分析做相關的探討，並根據疲勞理論分析皮帶內部應力與皮帶壽命。由馬達馬力、皮帶輪轉速、皮帶輪直徑及組成皮帶的橡膠特性，導出皮帶馬力與轉速關係的數學模式。接著設計出適合的皮帶疲勞試驗，得到疲勞壽命曲線(S-N Curve)，並由拉伸試驗得到皮帶機械特性，而建立出皮帶馬力轉速關係圖表，試驗中同時也可判別皮帶品質的差異性。最後，為了快速判斷皮帶運動時的機械性質，使用有限元素法分析運轉時皮帶的應力分佈。本論文將可建立適當的傳動皮帶規範圖表，並分析皮帶在運動中受力的分佈情況，模擬並預測皮帶破壞的情況。

Belts and chains are the most popular flexible transmission components in practice. Belts can be used in high-speed applications, and they are quieter in operation. A belt power transmission system includes belts and pulleys, and torque is transmitted through friction force between the driving and driven pulleys. When designing industrial belts, we need to specify the power to be transmitted, speed of operation, and the diameters of pulleys. Then, according to the cross section selection chart and the drive selection table in belts design manual, we can choose suitable belts for the application. In order to achieve better belt life and transmission efficiency, accurate cross section selection chart and drive selection table are necessary. This thesis aims to create the cross section selection chart and the drive selection table based on experimental data and to conduct stress analysis of belts using finite element analysis.
In creating the cross section selection chart and the drive selection table, we begin with the relationship between stress and belt life from fatigue theory. Second, we derive the mathematic model of the cross section selection chart and the drive selection table by considering power requirements, operation speeds, diameters of pulleys, and the properties of rubber. Finally, we conduct belt fatigue tests to construct the S-N curve and obtain the rubber properties from tensile tests. This thesis then sets up the cross section selection chart and the drive selection table for belt selections. Furthermore, this thesis applies the finite element analysis method to simulate stress and strain distribution in belts for determining the quality of belts, and the results substantially reduce the time needed to forecast the failure of belts.
