摘　　要：通过分析双桥油气悬架组的液压系统原理,建立全路面起重机双桥油气悬架组的7自由度数学模型,并基于AMESim仿真软件对其建立仿真模型。在4个车轮同时受载荷激励、单侧车轮受载荷激励和单桥车轮受载荷激励3种工况下,分析双桥油气悬架组的位移、加速度、系统压力、侧倾角和俯仰角的振动特性,以及不同阻尼孔直径对振动特性的影响,为双桥油气悬架组的研发提供参考。Simulation analyzing hydro-pneumaticsuspending bogie. A mathematic modelin 7 degrees of freedom was constructedfor bogie oil-air suspension in an all-terrain crane through analyzing prin-ciples of the hydraulic system while asimulation model was set up there-for onthe basis of an AMESim simulation soft-ware. Under 3 operational conditions, thehydro-pneumatic suspended bogies wereanalyzed of vibratory characteristics atthe displacement, acceleration, systempressure, incline angle and pitch angle,together with various retarding diametersas affecting the vibration, thus providinga reference for further R&D of the bo-gie's oil-air suspension.
