摘　　要：为分析结构参数对液压悬置动刚度和滞后角的影响,采用集总参数的方法搭建液压悬置的动力学模型;然后,分析惯性通道横截面积、惯性通道长度、上腔柔度、惯性通道液体惯性系数以及惯性通道液体阻尼系数对悬置特性的影响。结果表明,增加惯性通道的横截面积、长度、上腔柔度以及液体惯性系数,液压悬置的动刚度和滞后角峰值以及峰值频率均相应的增加;而改变惯性通道液体阻尼系数仅改变液压悬置动刚度和滞后角的峰值大小。To analyze the influence of structural parameters on the dynamic stiffness and lag angle of hydraulic mount,a lumped parameter method was employed to construct a dynamic model of the hydraulic mount.Subsequently,the effects of the cross-sectional area,length,upper chamber flexibility,liquid inertia coefficient,and liquid damping coefficient of the inertia channel on mount characteristics were analyzed.The results show that with the increase of the cross-sectional area,length,upper chamber flexibility and liquid inertia coefficient of the inertia channel,the peak values and peak frequencies of the dynamic stiffness and lag angle of the hydraulic mount increase accordingly;while changing the liquid damping coefficient of the inertia channel only influences the peak values of the dynamic stiffness and lag angle of the hydraulic mount.
