Research on the vibration isolation performance of low-frequency hydraulic engine mount

This paper aims to study the influence of decoupler membranes on the vibration isolation performance of hydraulic mount under low-frequency excitation. Firstly, the mathematical model of the hydraulic mount is constructed using the lumped parameters and the accuracy of the mathematical model is confirmed. Secondly, the influence of the dynamic characteristics and flow rate of the hydraulic mount under different excitation amplitudes and excitation frequencies is analysed. Finally, the hydraulic mount system of the 1/4 car model is built to analyse the effect of with or without decoupler membrane channels on the vibration isolation performance of the system from sinusoidal excitation, random road spectrum, and different engine speeds. The results of the study show that the decoupler membrane directly affects the hydraulic mount in low frequency vibration isolation performance.
