| 摘 要： | 针对航空制造业中,当容差分配问题中含有装配成功率等随机约束时,常用的数值算法往往难以处理。为提高产品制造精度,提出了混合蒙特卡洛(Hybrid Monte Carlo,HMC)算法,即把动态蒙特卡洛(Dynamic Monte Carlo,DMC)算法和静态蒙特卡罗(SMC)算法结合起来,将DMC用于容差分配的优化仿真运算,把SMC用来处理装配成功率约束。通过仿真验证了该方案的可行性,混合蒙特卡洛法既合理地处理了随机约束,证明装配准确度计算和容差分配的一致性。结果说明求解这类问题是最佳算法。

| Abstract: | When the random constraints,such as success probability of assembly exist,tolerance allocation usually becomes difficult for the numerical method.A hybrid Monte Carlo(HMC) algorithm is presented,that combines dynamic Monte Carlo(DMC) method with static Monte Carlo(SMC) method.That is,the optimization of tolerance allocation would be simulated by DMC,and the constraints of the success probability of assembly would be solved by SMC.A detail example of tolerance allocation is given to verify the ways and means... |
