摘　　要：为了研究电动轮自卸车轮边减速器行星架的结构可靠性,利用ANSYS的概率设计功能,以行星轮轴直径、行星轮传递给轮轴的压力及弹性模量为随机输入变量,模拟实际构件设计参数的随机性,选用蒙特卡罗法进行行星架的可靠性分析,得到该有限元分析模型的应力概率分布特征、应力累积分布函数和行星轮轴直径等设计参数对应力分布的敏感程度。研究所得结论对于改进电动轮自卸车轮边减速器结构设计、提高其使用寿命具有一定的作用。In order to study the structural reliability of motor wheel dumper wheel reducer planetary frame, using probability design function of ANSYS, the paper takes planetary axle diameter, the pressure of planetary gear transmission to axis and elasticity coefficient as random input variables, simulates the randomness of the actual design parameters components. Using the Monte Carlo method to analyze the planetary frame reliability, the stress probability distribution characteristics of the finite element analysis model, accumulation distributed functional arrangement and planetary, axle design parametem such as diameter, degree sensitivity of stress distribution are achieved. The research conclusion has a certain role in improving structural design of motor wheel dumper wheel reducer and enhancing the service life.
