Abstract
In order to study the effect of the interaction between different inertial channels and decoupler membrane channels on the hydraulic mount characteristic. Firstly, the effect of the single inertia channel and decoupler membrane channel interaction on the hydraulic mount characteristic is analyzed. Secondly, a multi-inertia channel hydraulic mount model with nine structures and four combination schemes is proposed. Among them, the mount's structure includes long inertia channels, short inertia channels, different inertia channel cross-sectional areas, and the number of inertia channels. And then, the number of inertia channels, the cross-sectional area, and the interaction between long and short inertia channels and decoupler membrane channels are analyzed for their effects on the hydraulic mount characteristics. Finally, the effect of the interaction between the inertial and decoupler membrane channels on the time-domain characteristics of the hydraulic mount at different excitation amplitudes. The results show that the number of inertia channels, cross-sectional area, and the interaction between the number of long and short inertia channels and decoupler membrane channels directly affect the vibration isolation performance of hydraulic mounts at high and low frequencies. Keywords: hydraulic mount, inertia channel, decoupler membrane channel, interactions.
