本文通过对HT-12Y型农用运输车半轴的弯、扭载荷进行实测和理论分析计算,编制了用于对半轴进行疲劳试验加载的弯-扭组合程序载荷谱,并对半轴在复合交变载荷作用下的寿命进行了估算。
In this paper, the bending and torsion loads of the axles of the HT-12Y agricultural transport vehicle are measured and theoretically calculated, and the load spectrum of the bending-torsion combination program for loading fatigue tests on the half shafts is compiled. The life under alternating load was estimated.
