摘　　要：为获得某轿车主减速齿轮尺寸参数对其传动可靠性的影响,提出采用改进拉丁超立方抽样(LHS)获取随机尺寸样本的方法;通过显式有限元仿真构建齿面最大接触应力完全二次响应面(RSM),研究了可靠度对参数的灵敏度。结果表明主减速齿轮可靠度对压力角和模数的均值与方差较为敏感,应合理控制其取值。In order to obtain the effects of size parameters on reliability of the main reduction gears in a car, an improved LHS was presented to acquire the random size samples. The full quadratic RSM of the maximum contact stress on tooth surface was built through explicit finite element simulations to study reliability sensitivity to the key parameters. The results show that the mean and variance of pressure angle and modulus which are more sensitive to reliability of the gears must be selected rea- sonably in design stage.
