| Abstract: | The main frame of steel structure was redesigned via computer simulation optimization,and magnesium alloy was used to reduce the weight of electric bicycle.The new frame structure and tube thickness were obtained by using topology optimization and size optimization respectively.At the same time,static analysis and mode analysis of the main frame were carried out.Compared with the original steel frame,the magnesium alloy main frame after optimization has reduced the mass by 60%,the natural frequency improves greatly.The results show that the strength and the rigidity of the new structure can meet designed demand. |
