以农用运输车减振为目的，建立了二自由度农用运输车油气悬架系统的数学模型，分析了油气悬架系统数学模型的非线性特性。运用AMEsim仿真软件，采用阶跃信号、谐波信号和随机信号模拟农用运输车典型行驶路况，对比分析了被动悬架和油气悬架的振动特性，验证了数学模型的正确性。通过比较两种悬架的振动特性、非线性特性和车身高度偏离静平衡状态的程度等3项指标，表明采用油气悬架可明显改善农用运输车悬架的振动性能，提高行驶平顺性和乘坐舒适性。
以農用運輸車減振為目的，建立瞭二自由度農用運輸車油氣懸架繫統的數學模型，分析瞭油氣懸架繫統數學模型的非線性特性。運用AMEsim倣真軟件，採用階躍信號、諧波信號和隨機信號模擬農用運輸車典型行駛路況，對比分析瞭被動懸架和油氣懸架的振動特性，驗證瞭數學模型的正確性。通過比較兩種懸架的振動特性、非線性特性和車身高度偏離靜平衡狀態的程度等3項指標，錶明採用油氣懸架可明顯改善農用運輸車懸架的振動性能，提高行駛平順性和乘坐舒適性。
