The fluid vibration isolator comprises a vibration isolator shell, an end cover, a hollow cylinder A, a hollow cylinder B, a translation rod, a piston A, a piston B, a flexible pipe, a compressive screw spring A and a compressive screwspring B, one end of the translation rod penetrates a linear bearing mounted on the end cover and extends outside the end cover, the piston A and the piston B are slidably mounted in the hollow cylinder A and the hollow cylinder B, one end of the compressive screw spring A is fixedly mounted in the middle of the inner bottom of the vibration isolator, the other end of the compressive screw springA is free, one end of the compressive screw spring B is fixedly mounted in the middle of the inside of the end cover, and the other end of the compressive screw spring B is free. The inside of a fluid chamber A is filled with viscidity fluid with shear thickening characteristics in an original state, and fluid is absent in a fluid chamber B. The fluid vibration isolator with symmetric vibration isolation is based on nano-particle solvent absorption energy.

Description

technical field [0001] The invention mainly relates to the field of fluid vibration isolators, in particular to a fluid vibration isolator based on nonlinear stiffness symmetrical vibration isolation. Background technique [0002] A fluid vibration isolator is a device that uses damping characteristics to slow down mechanical vibration and consume kinetic energy. Fluid vibration isolators in the prior art usually use current to control the viscosity coefficient of the fluid or change the working gap of the fluid to achieve the change of the damping force. Due to the asymmetry of the piston motion, the existing fluid isolators cannot achieve symmetrical vibration isolation with large damping force. Therefore, it is of great application value to design a fluid vibration isolator based on nonlinear stiffness symmetric vibration isolation.
