摘　　要：针对汽车传统悬架在汽车行驶平稳性和操控稳定性上存在的问题,提出了采用空气弹簧取代金属螺旋弹簧的空气悬架方法。对设计位置处空气弹簧的静刚度进行了理论推导,并通过ABAQUS软件建立汽车空气弹簧系统动力学有限元仿真模型。最后,对样件刚度的台架测试结果与有限元仿真结果进行了比较,结果显示:建立的模型有效地解决了空气弹簧静刚度计算的难题,提高了空气弹簧有限元仿真速度和计算精度。The method of air suspension using air spring to replace the metal coil spring was proposed,based on the traditional suspension application issues existing in the ride comfortable and handling control stability.The static stiffness of air spring at the design position was calculated theoretically,and the finite element simulation model of automobile air spring system dynamics is established by ABAQUS software.Finally,the stiffness of the bench test sample is compared with the finite element simulation results.The results show that the established model effectively solves the problem of calculating the static stiffness of the air spring and improves the speed and accuracy of the finite element simulation of the air spring.
