摘要
由于车辆轮边减速器实际设计中存在较多的不确定性因素,而其最终将会影响系统的质量,采用田口方法和模糊综合评判法相结合对不确定因素进行稳健性分析。根据轮边二级轮边减速器的结构特点,搭建其数学模型。建立轮边减速系统稳健型设计的目标函数,确定试验因素以及每个因素的水平数,建立合适的正交表安排试验方案,采用模糊综合评判方法对影响因素跨水平问题进行分析,获得最佳模糊评判参数,并将基于田口方法的稳健性设计和可靠性性设计水平指标、分析结果进行对比。分析结果表明,系统的体积减小,同时可靠性有一定的提高,同时与可靠性的优化设计对比,田口方法简捷方便更具有优越性。
For that there are many uncertain factors in the actual design of the vehicle wheel hub reducer, and it will eventually affect the quality of the system. The combining method of Taguchi method and fuzzy comprehensive evaluation method is used to analyze the robustness of the uncertain factors. According to the structural characteristics of the two stage wheel hub reducer, a mathematical model was built, and the objective function of robustness design of wheel hub reducer system was built. The test factor and the level of each factor were determined. A suitable orthogonal test plan of the test factor was established. Analysis of the cross level problem of influencing factors were carried out by using the fuzzy comprehensive evaluation method, and through that got the best fuzzy evaluation parameters. The level index and analysis results of Taguchi method and reliability design were compared. The results show that the volume of the system is reduced and the reliability of the system is improved. And through comparison, the Taguchi method of robustncss design is simple and convenient.
