结合装载机作业特点,通过对ZL40装载机半轴扭矩实测信号的分析,本文认为装载机半轴扭矩在单个作业循环中是非平稳的随机载荷。因而只有分段对典型工况分析处理,才能编制出符合实际的载荷谱。文中还给出了ZL40装载机后桥半轴的载荷谱实例。
Combined with the loader’s job characteristics, through the analysis of the torque measured signal of the half shaft of ZL40 loader, this paper believes that the load torque of half shaft of the loader is a non-stationary random load in a single working cycle. Therefore only the subsections can analyze and process the typical working conditions to compile the actual load spectrum. An example of the load spectrum of the rear axle half shaft of the ZL40 loader is also given.
