英文摘要：

One type of Electronically Controlled Air Suspension （ECAS） System with adjustable damper is studied. Based on the analysis of the structure and principle of the suspension, thermodynamics and fluid mechanics theory are used to establish the mathematic model of ECAS. In AMESim, the proper components and sub-models are chosen to establish the model of suspension system, and its performance is simulated to obtain ECAS stiffness and damping performance. The test of ECAS performance is done on the INSTRON 8800 test bench. The comparison between the simulation result and test result is done, which indicates that the model of ECAS can be used to study the performance of this type of ECAS.
