| 摘 要： | 对双滑块驱动无返回力矩钟表机构进行了理论分析，在VisualNastran软件环境下进行了该机构参数最佳匹配规律研究。采用正交试验和仿真研究该机构中双滑块质量参数最佳匹配、拉簧刚度和惯性簧刚度参数最佳匹配。仿真和试验结果表明：该机构可以有效区分导弹正常发射过载与勤务处理干扰环境力；能有效避免单质量块后坐保险机构的钟表机构在冲击试验中存在断齿的问题；该机构下滑块质量与上滑块质量最佳比为7.96、拉簧刚度与惯性簧刚度最佳匹配为2.75，此时在冲击和震动试验中上滑块位移响应和速度响应最小。

| Abstract: | The runaway escapement driven by two slide-blocks was theoretically analyzed,and the optimum matching law of the escapement parameters was studied by Visual Nastran software.The optimum matchings of up slide-block mass vs.down slide-block mass and pull-spring rigidity vs.inertia-spring rigidity were tested by orthogonal method and simulated.The simulated and tested results show that the escapement can effectively differentiate missile's overloading from disturbing force caused by environment at service hand... |
