交叉拉杆是转向架的关键部件之一,在车辆运行中承受横向、纵向和垂向载荷的共同作用。基于弹性有限元理论,利用有限元分析软件ANSYS对其进行在时速60km/h、80km/h、100km/h、120km/h的直线运行工况下的动应力仿真,由ANSYS求解器给出轴向应力和等效应力,根据所求得的应力结果,判定出交叉拉杆的危险部位,并分析其高应力区产生的原因,计算结果与文献[2]相符合,为今后交叉支撑装置的疲劳可靠性研究奠定基础。
One of the key components of the bogie is the cross-tie rod, which acts together with lateral, longitudinal and vertical loads during vehicle operation. Based on the elastic finite element theory, the finite element analysis software ANSYS was used to simulate the dynamic stress under the linear operating conditions of 60km / h, 80km / h, 100km / h and 120km / h. The ANSYS To the stress and equivalent stress, according to the obtained stress results, the dangerous parts of the cross-tie rod are determined and the reasons for the high stress zone are analyzed. The calculation results are in accordance with [2], which is the fatigue of the future cross brace Reliability studies laid the foundation.
