摘要:
针对某大型重载悬挂发射装置的挂钩解锁异常现象,对挂钩组件的磨损因素进行了实验和仿真研究。运用ADAMS动力学分析软件,对振动条件下的挂钩销轴在0.05 mm、0.1 mm、0.15 mm配合间隙的工况进行仿真分析。分别采用对比实验和单因素实验法,研究分析了轴孔配合材料、配合间隙和润滑条件对销轴磨损的影响。仿真结果显示,配合间隙在0.1 mm时销轴之间的接触碰撞应力最小,与实验结果相符,且在此种工况下销轴在挂钩孔中的转动效果最好。实验结果显示,挂钩和销轴采用同种材料时,销轴磨损较大; 销轴磨损随挂钩销轴与挂钩孔之间的配合间隙增大而增大; 挂钩销轴与挂钩孔之间采用7008航空润滑脂,可以减小配合面之间的摩擦,降低摩擦热量,减少销轴材料的磨损和烧蚀现象。
Abstract:
The wear factors of hook assembly of a large heavy-load suspension launcher are studied experimentally and simulated for the pin shaft abnormally unlocking. The working conditions of the hook pin shaft with clearances of 0.05 mm,0.1 mm and 0.15 mm under vibration condition are simulated using dynamic analysis software ADAMS. The influences of shaft and hole matching material,fit clearance and lubrication condition on pin shaft abrasion are studied by contrast experiments and single-factor experiments. The simulation results show that the contact collision stress between the pin and shaft is the smallest for the fit clearance of 0.1 mm,and the pin has the best rotation effect in the hook hole,which is consistent with the experimental results. The experimental results show that the wear of the pin shaft is greater for the hook and pin shaft using same material; the wear of the pin shaft increases with increasing clearance between the hook pin shaft and the hook hole; the 7008 aviation grease between the pin and the hook can reduce the friction between the mating surfaces,the friction heat and the wear and ablation of pin material.
