應用均勻實驗設計法及RBF神經網路模型於滾銷式齒形鏈系統之改良設計

齒形鏈最早應用在船隻螺旋槳動力系統中，最初的齒形鏈傳動機構其鏈輪與鏈片嚙合線段均為直線，而後經過許多工程師的改良才有現今各類型，齒形鏈因高傳輸效率、高轉速、低振動噪音的特點，目前已被廣泛應用於汽車傳動系統中，但因國內外於齒形鏈之公開研究較少，多數關鍵技術及專利多被國際大廠壟斷，故如何設計滾銷式齒形鏈便成為現今鏈傳動學術研究中重要的一環。本文應用逆向工程量測技術及動載分析軟體MSC.ADAMS建立一套滾銷式齒形鏈分析流程，以快速獲取鏈條波動量、接觸力與相對滑動速度等指標；此外，為了改善齒形鏈設計參數，本研究透過均勻實驗建立目標函數之RBF神經網路模型，並利用RBF神經網路模型取得齒形鏈最佳化之設計參數，最後透過MSC.ADAMS分析最佳化指標，最後與最佳化前之量測參數進行比較，針對齒形鏈耐久性及傳動效率不足之處給予設計改良及建議方案，以供業界作為滾銷式齒形鏈開發後用以評估及檢視設計。

Tooth chain is firstly applied in power system of ship propeller. The chain and tooth mesh sections in earliest tooth chain transmission mechanism are all straight, and developed for various types owing to the engineers’ improvement. Tooth chains have the advantages of high transmission efficiency, high rotating speed and low vibration noises and are widely applied in transmission systems of vehicles now. Nevertheless, the studies on tooth chains are relatively few, and most key techniques and patents are monopolized by international factories, so how to design roll-pin type tooth chain becomes an important topic of academic studies on chain transmission. This work adopts reverse engineering for measurement and dynamic load analysis software MSC.ADAMS to establish procedure for roll-pin type tooth chain analysis, so as to obtain the indexes such as the chain fluctuation quantity, contact force and relative sliding speed. In addition, to improve the design parameters of tooth chain, the study utilizes uniform experiment design to build a RBF neural network model for target function, by which the optimum design parameters of tooth chain is obtained. Finally, MSC.ADAMS is utilized to analyze the optimum index and compares the measurement parameters before optimization, so as to propose the improvement and suggestions for the shortcomings of durability and transmission efficiency. This work is feneficial for the evaluation and design of roll-pin type tooth chain.
