To alleviate the drivers’ physical injuries suffered of in the working environment, a novel vibration isolation structure with fluid is designed in this paper. Firstly, the analytical coupling model of fluid and rubber is proposed, and the amplitude–frequency response characteristics of vibration isolation system are analyzed. The influence of different parameters on the vibration transmissibility is studied. Secondly, the finite element model of strong nonlinear coupling is established to analyze the circulating flowing characteristics of fluid in the sealing chamber. Finally, the vibration isolation structure is experimentally studied and discussed. The results show that the absolute displacement transmissibility curves of the system obtained by practical measurements are in good agreement with those obtained by finite element modeling and analytical modeling, respectively, verifying the reliability of the two mathematical modeling methods. Meanwhile, it also proves that the designed structure can achieve full-frequency domain vibration isolation under random excitation, which provides a new idea for the subsequent structural optimization design, and effectively blocks the negative impact of high-frequency excitation on human health.
