Research On The Technology Of Magnesium Alloy Bicycle

Magnesium, the lightest of metals, its excellent features are more and more popular with people. Stylish, lightweight magnesium alloy bicycles have gradually replaced the traditional clunky bikes. All bicycle enterprises are active in the development and application of magnesium alloy bicycle technology, so the research and development of magnesium alloy bicycle frame technology is particularly important.Bicycle frame as the frame of the bike, which is the main body and the basic body of bicycle, it is also an important bearing parts, it bears most of the weight of people and goods, also stand the process of moving to the ground impact load. So, bicycle frame structure and properties will directly affects the safety of the rider, stable and light. Frame is the main structure of bicycle, which plays a role in connecting, supporting various components, and bears to its wide range of forces and moments, it must be sufficient reliability and longevity. In addition, frame quality and minimize to reduce vehicle weight. Because of this, this paper based on magnesium alloy MTB product of Hebi Pretty Bird Vehicle Industry Co. LTD. Actual surveying and mapping for the frame, using three-dimensional modeling software PRO/E, three-dimensional modeling of the frame. First with PRO/E5.0 CAD software to create the frame model, then the ANSYS finite element structural analysis of static strength, generate deformation maps, displacement maps, stress diagram, determine the maximum displacement, and the region of maximum stress, be checked, and then import the finite element analysis software ANSYS, frame structure for finite element simulation and optimization, resulting in structural design reasonable magnesium alloy bicycle frame.After structural optimization, the axial height of 30cm, and other major size under the condition of little change, two rounds of center distance optimization from 108cm to 102.5cm, the center distance decreases 5.5cm. The overall size of the frame has been reduced. Structural strength analysis, modal analysis and calculation results show that the optimization program to be effective, for the future of the bicycle frame design provides some useful experience.
