Influence of structural parameters on hydraulic mount characteristics of inertia channels
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.
