提速货车装用不平衡轮对后对交叉杆疲劳强度影响的分析

Crossing Bar Fatigue Strength Effect Analysis of Raising Speed Freight Car with Unbalanced Wheelset

根据对提速货车转向架在实际运用线路中装用平衡轮对和装用不平衡轮对在空车与重车的不同工况下应力测试数据,应用疲劳强度理论对转向架关键部件的疲劳强度进行计算,分析了提速货车装用不平衡轮对后对交叉杆疲劳强度的影响。

According to the tested stress data under different cases of empty wagon and loaded wagon of raising speed freight car＇s bogie with unbalanced and balanced wheelset in practical operation by applying fatigue strength theory to calculate the fatigue strength of the bogie＇s key parts, the effect to fatigue strength of crossing bar of freight car due to unbalanced wheelset is analyzed.
