摘　　要：根据实测的交叉杆的动应力,识别其上的载荷,提出了载荷组合的方法,利用这些载荷进行了有限元应力场的分析计算,最后应用MSC.Fatigue2001疲劳分析软件,用名义应力法对转8G型转向架交叉支撑装置的疲劳寿命进行了仿真计算,得到了99%可靠度下的疲劳寿命分布,与交叉支撑装置的实际使用寿命较吻合。The loads on the cross pole are identified based on the real measured dynamic stress.The way to (combine) the loads is given.Made use of these loads,the (finite) element analysis and calculation have been completed.The fatigue life simulating calculation of the cross sustaining device of Z8G bogie has been performed by using MSC (Fatigue) 2001 software in nominal stress method.And thus the distribution map of fatigue life at 99% reliability is abtained and it is correspondent to the real service life.
