摘要
为探究压铆螺母推广应用的可行性,本文通过静载力学试验,得出了压铆螺母CLS-M8-2的推出力、扭出力矩以及极限安装力矩;同时,基于不同应力水平进行了疲劳寿命测试,得到了CLS-M8-2的疲劳寿命数据,拟合了S-N曲线,总结了压铆螺母疲劳寿命规律;验证了压铆螺母CLS-M8-2的静力学强度、疲劳强度及应用可靠性。
In order to explore the feasibility of the promotion and application of the pressure riveting nut,In this paper obtained the push force,torque and limit installation torque of the pressure riveting nut CLS-M8-2 through the static load test.Meanwhile,the fatigue life test of CLS-M8-2 was carried out based on different stress levels,and the fatigue life data of CLS-M8-2 was obtained.The S-N curve was fitted,and the fatigue life law of riveting nut was summarized.The static strength,fatigue strength and application reliability of pressure riveting nut CLS-M8-2 are verified.
