| 摘 要： | 针对国内汽车空气弹簧市场需求,开发出由胶囊和减振器装配成一体的复合式空气弹簧,该结构产品取代传统的螺旋弹簧减振器,即解决了空气悬挂空间狭小的问题,又实现了空气弹簧的变刚度调节,大大降低悬挂系统的固有频率,提高了乘车的舒适性和稳定性。借助有限元分析软件进行汽车空气弹簧的性能参数计算,确定了半成品的裁断角度等技术参数,通过产品试验,验证了有限元计算及工艺参数选取的正确性。

| Abstract: | To cope with the demand of Air Spring in domestic market,a Compound Air Spring assembled with capsule and absorber was developed, the product have replaced conventional helical spring absorber, which solved the problem of narrowness in space caused by air suspension,. A compound air spring can also reduce the natural frequency of suspension system by changing the stiffness of air spring and increase the stability and comfort. The air spring parameter by FEM software determined the cutting angle of semi-pro-cessed product,and the correctness of FEM calculation and the selection of the parameter was certified by experiment of product. |
