摘要
大型行星齿轮传动系统工况复杂,安全性能要求高,常规的设计方法因过于注重安全性,设计的结果偏于保守,技术经济指标不佳.以行星齿轮传动系统为对象,提出了大型机构可靠性设计的多目标优化模型,即以齿轮的关键参数——齿数、齿宽、模数为设计变量,充分考虑工程设计的约束性、多解性等特征,建立数学模型,进行可靠性分析计算,并在MATLAB优化工具箱里采用积极集策略进行多目标优化.将得到的结果与传统设计方案结果相比较,为大型行星齿轮系统的优化设计提供新思路.
Due to extremely-complex working conditions and highly-demanding safety performances,the conventional design methodologies with extensive safety considerations tend to be intensively conservative,i.e.low technological and economic performances.Pertaining to the planetary gear transmission systems,a multi-objective model for reliability design is proposed for large-scale mechanisms.In details,the enabling gear parameters,e.g.tooth number,width and module,are treated as random variables to fully consider such engineering design characteristics as constraints and multi-solutions.In this fashion,the mathematical model is established for reliability analysis and calculation.Meanwhile,the multi-objective optimization is conducted using active set method via MATLABTM toolbox.Compared with the traditional design methodologies,this approach provides a new design conception for large-scale planetary gear transmission systems.
