摘　　要：将可靠性优化设计理论、可靠性灵敏度技术和稳健设计方法相结合,讨论了具有任意分布参数的刨煤机刨链与链轮运动精度可靠性稳健设计问题,提出了可靠性稳健设计的数值计算方法,在基本随机参数的前四阶矩已知的情况下,采用NSGA-Ⅱ算法编制计算机程序实现刨链啮合运动精度可靠性稳健优化设计,基于所建立的刨链啮合运动模型,给出运动机构的稳健优化设计实例,验证该方法能够准确得到刨链啮合运动机构的设计信息。By combining the reliability-based optimization design theory,the reliability sensitivity technique and the robust design method,the reliability-based robust design for the kinematic accuracy of the plow chain with arbitrary distribution parameters was discussed extensively.Subsequently,a numerical method for reliability-based robust design was proposed.Under the condition that the first four moments of basic random parameters are available,NSGA-Ⅱalgorithm computer programs based on this model can be used to complete the reliability-based robust design for kinematic accuracy of plow chain accurately and quickly.Based on the proposed models,an example shows that the proposed method is practical and effective.
