摘要： 轮边减速器传动系统作为轮毂驱动系统的核心部件,其可靠性直接影响轮毂驱动系统乃至整车的运行可靠性和工作寿命.针对现有轮边减速器传动系统可靠性评估只考虑单一齿面失效或齿根失效的不足,提出考虑二者失效相关的动态可靠度计算方法.首先,在考虑齿轮材料强度退化的前提下分别建立齿面、齿根强度退化随机模型;然后,基于应力-强度干涉理论并采用Monte Carlo方法计算得到2种失效形式下考虑强度退化的齿轮动态可靠度曲线;其次,根据Copula理论建立同时考虑2种失效形式相关性的单一齿轮动态可靠度数学模型;最后,应用Sklar定理对零件失效过程的相关性进行描述,建立轮边减速器传动系统动态可靠度数学模型.通过算例验证结果表明:该方法能够揭示多失效形式和多因素相关条件下系统疲劳寿命与各零部件疲劳寿命之间的关系,可以为轮边减速器传动系统的可靠性评估和预测提供理论依据.

Abstract: The wheel reducer driving system is the core component of the wheel hub drive system, which reliability directly affects the operating reliability and working life of the entire drive system. In view of the deficiency that only single tooth surface failure or tooth root failure is considered in the reliability evaluation of the existing wheel reducer transmission system, a dynamic reliability calculation method considering the correlation between the two failures is proposed. Firstly, a stochastic model of the strength degradation of tooth surface and tooth root is established respectively on the premise of considering the strength degradation of gear material. Secondly, based on the stress-strength interference theory and the Monte Carlo method, the dynamic reliability curve of the gear considering the strength degradation is calculated for both types of failures. Thirdly, a mathematical model of the dynamic reliability of a single gear is derived based on Copula function. Finally, the theorem of Sklar is applied to describe the correlation of part failure processes to obtain a mathematical model of the dynamic reliability of the wheel reducer driving system. The results of verification by calculation example show that this method can reveal the relationship between the fatigue life of the system and that of each component under multiple failure modes and factors. This method can provide a theoretical basis for the reliability evaluation and prediction of the wheel reducer driving system.

Key words: driving system, strength degradation, failure correlation, dynamic reliability mathematical model
