The performance of suspension directly affects travel property, safety, comfort and maximum velocity of vehicles. This is much more important for the special vehicles such as crane. In this paper, theoretical analysis have been performed for both the structure and the performance of hydro-pneumatic suspension system in crane. A nonlinear mathematical model for it is developed in which the oil compressibility is considered. With the language of MATLAB, Computer simulation has been used .With the full road experimental equipment produced by Company SCHENCK of Germany, the test has been done .The comparison between the simulative results and experimental results has proved that the nonlinear mathematical model developed and the program are believable .So some innovative conclusions have been obtained .This is beneficial to the design and modification of crane and its suspension .In addition ,many other related systems also can draw lessons from this research in the future.
