摘要
介绍了一种基于统计推断进行结构疲劳可靠性评估的方法。以某型高速列车动车转向架构架为例,采用该方法得到了构架的扩展应力谱,分析了其疲劳寿命。
A method of structure fatigue reliability evaluation based upon statistic inference is described.With the bogie frame for powered car in a certain type of high speed trains as the example,the spreading stress spectrum of the bogie is obtained with the method,and the fatigue service life is analyzed.
