摘　　要：随着齿轮传动系统向着高复杂性、多传动样式和高可靠性等方向发展,快速准确地对齿轮传动系统进行可靠性分配变得越来越重要。针对现有可靠性分配方法存在的考虑因素不全面、同一参数不同分配方法变化范围不统一、不便于数字化软件开发等问题,提出了改进电子设备可靠性咨询组(Advisory Group on Reliability of Electronic Equipment,AGREE)分配法,扩展了评分分配法;探讨了可靠性分配方法的数字化特征,建立了齿轮传动系统的基本可靠性与任务可靠性模型,研究了可靠性模型自动生成的遍历算法;开发了定轴轮系、行星轮系和混合轮系可靠性快速分配的数字化平台,设计了输入模块、计算模块、结果显示模块和输出模块等4个独立模块;通过与实例结果的比较,该软件计算结果的准确性得到了验证;同时也实现了齿轮传动系统可靠性分配的参数化建模与自动化生成算例报告等功能,提高了可靠性分配模型精度和计算效率。With the development of the gear transmission system towards complexity,multiple transmis⁃sion types and high reliability,it becomes more and more important to assign the reliability of the gear transmis⁃sion system quickly and accurately.In this study,aiming at the problems of incomplete consideration factors,in⁃consistent range of changes in different allocation methods for the same parameter,and inconvenient digital soft⁃ware development in existing reliability allocation methods,an improved advisory group on reliability of electron⁃ic equipment(AGREE)allocation method is proposed,the scoring allocation method is extended,and the digital characteristics of reliability allocation method are discussed.The basic reliability model and task reliability mod⁃el of the complex gear transmission system are established,and the traversal algorithm of the automatic reliabili⁃ty model generation is studied.A digital platform for rapid reliability allocation of fixed axle gear train,planetary gear train and hybrid gear train is developed.Four independent modules,namely input module,calculation mod⁃ule,result display module and output module,are designed.The accuracy of the calculation results of the soft⁃ware is verified by comparing with the results of examples.The parametric modeling and the automatic genera⁃tion of the example report for the reliability allocation of the gear transmission system are realized,and the accu⁃racy and efficiency of the reliability allocation model are raised.
