The fatigue problem has become one of the important researches on the design of auxiliary frame of the agitator truck. Combining the ESLs structural optimization method ,topology optimization method with fatigue prediction, a fatigue design method, which can get sound topological structure through dynamic topology optimization, was put forward in the initial stage of part design to make components satisfy the design requirements on fatigue life and lightweight at the same time. Firstly, an optimization model whose accuracy was verified by experiments was established to analyze the transient response of agitator trucks . Then, with the road spectrum generated and the fatigue life of the key point was evaluated. Finally, the fatigue design was conducted under the influence of the simplified pavement spectrum and gravity.. The fatigue design of the auxiliary frame indicates that the application of this method for structural fatigue design can get more reasonable structure components, which achieves the goal of fatigue design.
