A method for testing an air-spring was advanced in the beginning. Then ANSYS was utilized to simulate the static test. In the simulation, multiple load steps solution was carried out through APDL *DO-LOOP and array parameter method. Scalar parameter PRESSURE was established as inner pressure tracking parameter to update inner pressure. Table parameter PRESSURES was established as inner pressure output parameter to export inner pressure of each load step. Comparison was done between simulation result and test data to prove the feasibility of simulation. Finally, some major parameters such as cord angle and initial inner pressure were taken into account, which had remarkable effect on the air-spring’s performance.
