为了弥补传统的设计方法带来的缺陷 ,将蒙特卡洛方法引入枪械零件的可靠性设计与分析。该文概括了机械零件可靠性设计中的蒙特卡洛方法 ,阐述了蒙特卡洛法解决可靠度干涉问题和分布类型综合问题的一般途径 ,探讨了其在枪械零件强度可靠性分析中的应用 ,并以圆柱螺旋扭簧和枪机闭锁凸笋的可靠性设计实例验证了其科学性和合理性。实践证明 ,这种方法不仅可以提高产品的可靠性 ,而且可以在一定程度上优化设计结果。
In order to make up for the defects brought by the traditional design methods, the Monte Carlo method is introduced into the reliability design and analysis of gun parts. This paper summarizes the Monte Carlo method in the reliability design of mechanical parts, expounds the general approach of Monte Carlo method to solve the reliability interference problem and the distribution type synthesis problem, discusses its application in the strength reliability analysis of the gun parts, The reliability design example of cylindrical helical torsion spring and bolt latching shots validated its scientificity and rationality. Practice has proved that this method can not only improve product reliability, but also to some extent, optimize the design results.
