| 摘 要： | 本文利用空间梁单元作自行车构架的动力分析。推导了碰撞时的冲量公式，据此离散并计算数值，计算结果表明：上接头、上管前部、前叉是整个车架的高应力区，车架的强度受其制约。

| Abstract: | Based on the space-bar element, the dynamic analysis of bicycle frames is carried out. and the bump impulse equation derived. The stress distribution calculated according to this equation show that the up-joint, up-pipe front and pro-fork arm are the high stress areas on which the strength of the bicycle frame mainly depends. |
