摘　　要：针对全因子试验计算多组成环尺寸产品装配成功率试验次数较多、计算工作量较大等不足,提出一种基于Taguchi正交试验的产品一维装配成功率计算方法.首先根据Taguchi参数设计准则,将一维尺寸链中组成环尺寸作为Taguchi正交试验的因素,每个因素分为3个水平,制定正交试验表,进行正交试验,求解封闭环尺寸的均值和标准差,经计算获得装配成功率,然后采用极值法分析了各因素对装配成功率的影响.最后,以齿轮组件为实例运用Taguchi正交试验计算装配成功率,应用蒙特卡洛模拟法进行对比分析,结果表明该方法的有效性.这为产品一维装配成功率计算提供了一种新的途径.Evaluation method for one-dimensional assembly yield based on Taguchi orthogonal experiment was presented to solve the problem of the experiment number and the calculation amount in full factorical experiment.First,according to theTaguchi parameter design,component loop sizes were taken for factors of Taguchi orthogonal experiment,each factor was divided into three levels.After approriate orthogonal experiment table was selected,orthogonal experiment was operated.Then the mean and standard deviation,which were used to obtain assembly yield,of close loop size,were solved.The influence on assembly yield of each factor was analyzed by using extreme value method.Finally,taking a gear component asemmbly for example and the results were validated by using Monte Carlo Simulation.It provides a new way to calculate one-dimensional assembly yield of mechnical product.
