In order to solve the question of crack of the auxiliary frame of mixer truck, especially with the life of the triangle welding position is low, the triangle support of auxiliary frame optimization design is put forward Firstly, three dimensional structure model of auxiliary frame is established by Pro/E and the model is imported into HyperMesh software for meshing. The solver RADIOSS is used to calculate the maximum stress and the positions at the different full load conditions. Including the static, left front wheel lifted up by 210 mm, the right rear wheels (double) lifted up by 210 mm and the left front and right rear wheels lifted simultaneously up by 210 mm. Then the experimental vehicle test is performed. The test results and simulation results are compared and show a good consistency and the accuracy of the finite element model is validated. Then the three optimization design schemes of the triangle are put forward and the maximum stress of the optimal auxiliary frame are calculated in contrast with the original stress. The scheme 2 is found to be the most optimal, which provides an effective method for solving the fatigue of the auxiliary frame.
