Abstract: It is hard to measure the load history of the working device of hydraulic excavator in fatigue analysis. To solve this problem a novel fatigue analysis method is proposed. First, the complete change process of digging resistance, named Digging Resistance Load Spectrum (DRLS), is obtained by simulating the digging process of soil with the bucket of hydraulic excavator. Second, according to the DRLS, the load history of each hinge of the working device is calculated by the operation simulation of a full typical working cycle of the excavator. The simulation results are then verified by comparing with the actual cylinder pressure measured from the experiment similar to the working condition in the simulation. Finally, the fatigue analysis of the boom and arm of the working device are accomplished with the verified load histories of the hinges. The effectiveness of the proposed method is demonstrated with the fatigue analysis process of the working device of a 23 t hydraulic backhoe excavator. The results come out that the minimum lives of the boom and arm are 105.978 and 106.47 cycles respectively.
