车架设计时采用有限元分析很有必要，它可以预测车架设计时的强度问题，进而通过有限元优化设计尽可能避免；车架的细节设计，尤其是焊接位置的细节设计对整车强度有重要影响，稍有不慎会引起整车强度出现问题。因此，实际焊接方式应尽量采用理论优化后的焊接方式，尽量避免应力集中现象发生。

The infinite element analysis in necessary during the design of motorcycle frame. It can forecast the strength of frame. The determination of welding points is very important in the design. It has great influence on the strength of the whole motorcycle. Therefore, the optimization of weld is necessary during the design. The stress concentration should be avoided.
