【摘要】：针对弹簧质量块式加速度开关普遍存在过载值精度低、生产调试过程中动作过载值易发生偏移问题。文章对典型压缩弹簧质量块式加速度开关建立了力学方程,分析了弹簧弯曲角度、摩擦系数等机械参数对加速度开关的过载性能影响。得出压缩弹簧质量块式加速度开关的弹簧弯曲角度及摩擦系数对加速度开关过载性能的影响规律。得出加速度开关质量块与导向结构之间的摩擦系数ε0.04,加速度开关的压缩弹簧与导向结构中心轴之间的夹角θ1和θ2绝对值小于3°,能够使得加速度开关合格率达到90%以上的结果,对于产品生产控制提供了参考数据。
[Abstract]:In view of the low precision of overload value in spring mass block accelerometer switch, it is easy to offset the action overload value in the process of production and debugging. In this paper, the mechanical equation of the typical mass block acceleration switch of compression spring is established, and the influence of mechanical parameters such as spring bending angle and friction coefficient on the overload performance of the acceleration switch is analyzed. The influence of spring bending angle and friction coefficient on overload performance of compression spring mass block accelerator is obtained. The results show that the friction coefficient 蔚 0.04 between the mass block of the acceleration switch and the guide structure, the angle 胃 1 and 胃 2 between the compression spring of the acceleration switch and the center axis of the guide structure are less than 3 掳, and the qualified rate of the acceleration switch can reach more than 90%. It provides reference data for product production control.
