自行车的前管角、前叉弯度和轮距是设计自行车的主要参数,它们对车架的强度和自行车的性能有较大的影响。本文采用结构力学的有限元法,编制成电算程序,对沈阳自行车厂提出的四种不同的前管角、前叉弯度和轮距的自行车车架进行了静强度计算,并对计算结果作了详细的分析,为生产自行车的厂家提供了有益的设计资料。 The front angle of the bicycle, front fork pitch and track are the main parameters of the design of the bicycle, they have a greater impact on the strength of the frame and the performance of the bicycle. In this paper, finite element method of structural mechanics was used to calculate the static strength of bicycle frame with four different types of front tube angle, front fork and wheelbase proposed by Shenyang Bicycle Factory. The calculation results A detailed analysis of the production for the bicycle manufacturers to provide useful design information.
