摘要
探讨了接触应力分析在小型折叠弹翼动力学仿真中的应用,建立了折叠翼与折叠翼盒上下结合面、转轴与转轴孔之间的连接的接触模型,通过非线性接触分析计算接触面上的接触应力,然后就可以获得接触面上的摩擦力,因而较好解决了小型折叠翼的动力学仿真中的摩擦力确定问题,获得了满意的结果,本方法对小型折叠弹翼的机构设计有一定的参考价值。
The application of contact analysis to the dynamic simulation of deploying mechanism of a small-wing is researched, and an approach for evaluation of the friction of deploying mechanism is pro- posed. The contact models are established between the surfaces of wings and clipping base and the surface between revolving shaft and hole. The contact stress is computed by using nonlinear contact analysis. Then the forces of friction on the contact surface can be obtained. The simulation shows that the method is reliable and good results have achieved.
