Characteristic of All-Terrain Crane (ATC) is introduced in this paper and the working principle of Hydro-Pneumatic Suspension (HPS) in ATC is also discussed. The development status and tendency are summarized, through which we can see there is a large technology gap between China and Western Europe. An optimization method to HPS based on ADAMS is introduced in the paper. Based on ADAMS, a single bridge HPS of All-Terrain Crane virtual prototype is built and the function of HPS is accomplished with the standard hydraulic components. By the method of Design of Experiments (DOE), the dynamics optimization of HPS is carried out based on the analysis of the affecting factors after optimization variables are chosen. At last the result indicates that the dynamics characteristic of optimized model performs better than the former one and the present method can be used as a structural optimization reference.
