Abstract：This article uses multibody dynamics to analyze the force direction and force of the front and front pull rod of A frame of the 830 E dump truck, and loads the load under the worst working environment of the A type frame. The stress of A frame is obtained by the finite element method, and the stress is put into the stress to compare with the experimental test stress of A frame.The comparison results show that the error of the finite element analysis results is in the allowable range, and the reliability of the finite element model is proved. The topology optimization of the model is applied to the topology optimization of the optimized model, and the optimized A frame has the greatest stress. The force is reduced by 20.1％, the self weight is reduced by 7.2％, and the stress of A frame is evenly distributed.
