Synchronous test platforms were built to test the dynamic stress and working device attitude. The dynamic stress spectrums of all the test points under a variety of common conditions were obtained. The digging gestures corresponding to the peak of the dynamic stress spectrums were found out and taken as the specified digging gestures for the calculation of the static stress. The static stress nephogram of working device under the specified digging gestures was calculated using traditional static strength analysis. By conducting statistical analysis on the ratio of dynamic stress and static stress of all the testing points. Then, the range of generalized dynamic factor of working device was obtained.
