摘要：

To simulate the loader driving axle fatigue tests more realistic loader actual operation situations， a torque load spectrum compiling method of fatigue tests for loader driving axles was researched. In the compiling processes of the torque load spectrums， the loading method of former transmission shaft forword and reverse was proposed according to the actual torque characteristics of the loader driving axles. Subsequently the levels of load spectrum， the load threshold and the rotational speed of fatigue tests were determined. The results show that the equivalent effects of the theoretical treatment by the loading method of former transmission shaft forword and reverse are consistent with the actual operations of the loader， which may reduce fatigue test difficulties largely. The selection method of rotational speeds for the former transmission shafts in the fatigue tests may get the fatigue tests more realistic to simulate the actual operation of the loader. Loading an intensified fatigue test load spectrum of 11.4 h is equivalent to the actual operation of the loader for 609.2 h， which means that the fatigue test processes of driving axles are accelerated greatly. © 2018, China Mechanical Engineering Magazine Office.
