摘　　要：介绍了空气弹簧的试验方法和试验装置,采用ANSYS对空气弹簧的静态试验进行模拟分析。模拟过程利用APDL中的*DO-LOOP循环和数组参数法对空气弹簧进行多载荷步求解,设定标量参数PRESSURE作为内压跟踪变量以更新胶囊内壁的气压载荷,设定表格参数PRESSURES作为内压输出变量以输出每一个载荷步的胶囊内压。将模拟结果与试验结果进行了比较,证明了模拟的可行性。最后考虑并研究了帘线角、初始内压和附加容积等主要参数对空气弹簧静态力学性能的影响。A method for testing an air-spring and tester were introduced, 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. Simulation result and test data were compared to prove the feasibility of simulation. Finally, some major parameters such as cord angle, initial inner pressure and additive volume were taken into account, which had remarkable effect on the air-spring＇s static performance.
