| 摘 要： | 以汽车空气悬架非线性振动为研究对象，建立了微分方程，进行了理论分析和试验验证。研究表明空气悬架非线性强迫振动不仅在激励频率接近系统固有频率时出现主共振，而且还出现接近固有频率整数倍或分数倍时的次谐共振或超谐共振，汽车空气悬架非线性振动微分方程具有谐波组合形式的近似解，振动的中点不再是s=0处，即振动对于坐标原点不对称。

| Abstract: | The air suspension nonlinear vibration was researched in this paper.The nonlinear vibration differential equations of air suspension were established,and theoretic research and test validation were carried out.There will be resonance vibration for linear spring suspension when pumping frequency equal to natural frequency.But for air suspension nonlinear vibration,the output frequency is integer multiples of the pumping frequency.The air suspension vibration wave's mid-position is not on s=0 point.The vibration wave is dissymmetic to the equilibrium position. |
