高速客车转向架悬挂参数灵敏度及耦合关系探讨

Sensitivity and Coupling Relationship Analysis of Suspension Parameters of High-speed Bogie

列车速度达到200km/h以上时,属高速范畴。如何对高速转向架各参数进行分析,选择合理的参数组合,同样是一个值得探讨的问题。本文采用数理统计中正交试验分析方法,利用MEDYNA、NUCARS软件计算工具,对高速(200km/h)转向架悬挂参数的灵敏度和耦合关系进行了分析。在分析灵敏度和耦合关系的基础上,遵循一定的原则得出一组优选参数组合,对优选参数组合进行了仿真计算,计算结果表明优选组合的可靠性和分析方法的有效性。

When the train speed is more than 200km/h, it is belong to the high - speed category. It is worthwhile to probe into this problem, how to analyze the suspension parameters and select the reasonable parameters. This paper analyzes the sensitivity and coupling relationship of the suspension parameters of high - speed bogie, by the orthogonal method and MEDYNA NUCARS software. Under the foundation of analysis about the suspension parameters sensitivity and coupling relationship, according to a certain rule, this paper put forward the reasonable parameters combination and calculated with them. The calculation results express the reliability and effictiveness of this reasonable parameters combination.
