摘要
详细讨论了轴向受载的剪切弹簧的横向受力和位移,提出了轴向力和横向刚度之间的关系,建立了弹簧的系统方程,并由此推导出剪切弹簧元件的横向力学模型。同时还举例介绍了剪切弹簧模型的实际应用和计算,给出了不同轴向受载工况下的结果,以加深对剪切弹簧模型实际效果的理解。
The lateral force and the displacement of the shear spring with vertical load are discussed in detail. The relation between the vertical force and lateral stiffness is put forward. The system equation of the springs is set up. And the lateral mechanics model of shear spring elements is deduced. In the mean time, the practical application and calculation of the shear spring model are described with exam-ples, and the results under different working conditions of vertical load are given, so as to deepen the understanding of actual effects of the shear spring model.
