摘要：
A molecular spring isolator consisting of water, hydrophobic zeolites and a cylinder-piston container is introduced in this paper. When the molecular spring isolator undergoes periodic excitation, water molecules will intrude into hydrophobic pores of zeolites as hydraulic pressure reaches a critical level. And water molecules extrude from the hydrophobic pores as the pressure decreases. As a result, mechanical energy is stored, released and partially dissipated with the hydraulic pressure changing periodically. The stiffness model of molecular spring is established by two steps. Firstly, the mechanics model of water column intruding into a hydrophobic pore was established utilizing force equilibrium. After that, the process of water infiltrating a large number of hydrophobic pores was investigated. As a result, the stiffness of molecular spring isolator is piecewise nonlinear. Furthermore, a quasi-static experiment was conducted to verify the mechanics model and the effect of quantity of zeolites and temperature on molecular spring isolator was tested. Finally, the vibration isolation property is assessed by energy transmissibility.
