| 摘 要： | 针对目前研究弹性钢索中应力波传播规律时忽略纵波与弯折波相互作用影响的问题,文章从理论研究的角度介绍了纵波与弯折波相互耦合作用的机理和计算方法,并采用该方法进行了弹性钢索四次冲击应力的分析计算。结果显示,计算结果与文献中试验观察现象一致,从而验证了该计算方法的有效性。

| Abstract: | For the problem of ignoring the interaction influence of longitudinal wave and kink wave when researching the stress wave propagation law in the elastic cable, the principle and calculation method for coupling of longitudinal wave and kink wave is solved from the theory research aspect in this paper. The analysis and calculation of elastic cable fourth impact stress is made with this method, the calculation results agree well with the experimental observations of the literatures, and verify the validity of the calculation method. |
