Design And Dynamic Analysis Of New Mountain Bike

Based on the analysis of existing mountain bikes and the study of female products, this paper finds out the ergonomics defects of existing mountain bikes and puts forward the improvement scheme of mountain bikes, meanwhile summarizes the mountain bike’s design steps and ergonomics the scope of the framework to determine the principle. A new type of mountain bike frame is designed with the aim of modern metropolitan bicycle. Through the evaluation of the comfort range of the human joint activities, ensures the comfort of the mountain bike when riding the joint activities, and through the human body size data designed cushion and handle. Secondly,the finite element method is used to analyze the static deformation and stress distribution of the frame, and ensure the safety performance of the frame. The results show that the design of the frame in terms of strength and stiffness are in line with the requirements to determine the structure of the largest stress in the site, and to change the wall thickness and change the shape of the way to optimize the frame, through the use of the same frame The influence of the material, the cross-sectional shape and the cross - sectional area on the strength and vibration of the mountain bike was analyzed by comparing the performance of the same material with the same material. It is concluded that the mechanics is not affected by the material, mainly the wall thickness and the cross-sectional shape. The vibration frequency is mainly affected by the material and the cross-sectional shape. The project design has some reference value. And evaluated the mountain bike in different levels of road vibration performance, according to the evaluation of the human body to assess the relevant national standards on the design of the bike comfort evaluation, and ultimately get the quality of light and comfortable mountain bike, and gives the vehicle model And color it.
