Pneumatic suspension is the most significant subsystem for an automobile. In this paper, a simplified and novel pneumatic spring structure with only conical rubber surface presented designed to reduce influence of external factors besides pneumatic. The nonlinear stiffness analyzed based on ideal gas model material mechanics. Natural frequency analysis transmission rate are obtained as two effect criteria dynamic model. vibration isolation system platform established in both simulation prototype tests. With results from simulation, rules analyzed, optimal function mass pressure achieved. experiment show be effective. This achievement will become important basis future research concerning precise active control vehicles.
