At the same time, the reflection characters of strain wave and displacement wave are analyzed at the fixed end, free end and elastic bearing end.

同时，本文分析了位移波和应力波在固定端、自由端和弹性支承端的反射特点。

Results The load-bearing stress, buckling stress, rotation stress have greater impact on the jiggle of the armor plate fixed fracture broken end.

结果承重应力、屈曲应力、旋转应力对钢板固定的骨折断端产生较大微动。
