| Summary: | 碩士 === 大葉大學 === 自行車創新產業碩士專班 === 107 === In study target to improve the high crown aluminum alloy , and explore the possible occurrence of various aspects of process . Generally, the method of manufacturing a low crown aluminum wheel frame is relatively easy, but when the crown height aluminum wheel frame is higher than 40 mm, the product is prone to defects dents will resulting in poor yield of the finished product. The research hopes that the paper results can improve the product manufacturing technology, and thus achieve the improvement of the finished product yield, and even the ability of the OEM to become OBM.
In this study, the aluminum alloy material used was 6061, and the software was used in the ANSYS dynamic module.Setup material is used bilinear isotropic , because we don’t consider ultimate strength.In addition, the mechanical properties of the material are obtained according to the tensile test ASTM E8 method. Plasticity resolve method used Finite Element Method . Study uses Computer Aided Design to explore the rolling wheel diameter rolling angle combines it with the three-point arcing . The optimum roller diameter wheel set is obtained to improve the defects.
