In response to call for energy conservation and emissions reduction, and the lightweight design on auxiliary frame of mixer truck is put forward. The FEA model is built by HyperMesh software to mesh, then the solver Radioss is used to calculate respectively the maximum stresses and the positions at the different full load conditions, including the static, left front wheel up 210mm, the right rear wheels up 210mm and the left front and right rear wheels simultaneously up 210mm. Then the real vehicle test is done, and the test results and simulation results have the good consistency, and the accuracy of the finite element model is validated. On the basis of these, the optimization design scheme of the thin material, oblique support and else local optimizations are put forward, analyzing again, the results are obtained that the total quality of the frame decreases to 10%, at the same time the strength also increases a little. Which provide an effective method for developing the optimization of vehicles, and make an important contribution for “energy saving emission reduction”.
