| 采用非线性有限元分析软件Abaqus建立汽车用空气弹簧的模型，并对其垂向特性进行模拟分析。结果表明：空气弹簧的垂向载荷随充气压力的增大呈线性增大，定值充气压力下随帘线角度的增大而减小；最大外直径和最大应力随帘线角度的减小而增大；垂向静刚度随充气压力的增大而呈线性增大，随帘线角度的增大而减小，定值充气压力下随工作高度的增大先减小后增大，存在一最小刚度。试验验证了有限元分析结果的正确性。 |
| 英文摘要: |
| The finite element model of air spring for vehicles was established with non linear finite element analysis software Abaqus to simulate and analyze its vertical characteristics.The results showed that，the vertical load was increased linearly with the increase of inflation pressure，and decreased with the increase of cord angle under the same pressure.The maximum outer diameter and stress increased with the decrease of cord angle.The vertical static stiffness increased linearly with the increase of inflation pressure，decreased with the increase of cord angle，and decreased with the increase of operational height firstly and then increased when the height continued to increase，i.e. there was a minimum stiffness value.The simulation results were confirmed by tests. |
