| 摘 要： | 建立了具有优越的隔振特性的双气室油气悬挂的数学模型，基于谐波平衡法推导出了悬挂系统的等效刚度和等效阻尼表达式.公式表明等效刚度和等效阻尼是激振频率和响应振幅的函数.分析了悬挂系统的主副蓄能器刚度和节流阀阻尼系数等关键参数对于等效刚度和等效阻尼的影响，并通过双气室油气悬挂特性实验验证了数学模型的准确性.

| Abstract: | With excellent isolation performances, hydro-pneumatic suspensions are widely em-ployed as vibration isolation system in many engineering field.The dual-chamber hydro-pneu-matic suspension is a modified version of the traditional hydro-pneumatic suspension.The ex-pressions for the equivalent stiffness and damping coefficient were derived from the modeling of dual-chamber hydro-pneumatic suspension expressed by a set of differential equations.Both the equivalent stiffness and damping coefficient show their strong dependency on the excitation fre-quency and amplitude.Based on the harmonic balance method,the effects of three key parame-ters,the stiffness of two accumulators and the damping coefficient of throttle,on the equivalent stiffness and damping coefficient were analyzed.The validity of the expression was confirmed through experiment result. |
