| Abstract: | In order to compile the loading spectrum of wheel loader and determine the fatigue life of transmission system,the torque load of transmission system of ZL50 wheel loader was tested.The true value of torque was marked by linear fitting method.The signals were processed by filtering and removing abnormal spikes.The frequency of low-pass filter was determined to be 1 Hz.The pure random load-time course is acquired,which consists with the actual work of loader. |
