Abstract: The present invention provides an adaptive vibration isolator. The adaptive vibration isolator includes a hydraulic system, a first elastic member, a second elastic member, an upper top plate, and a vibration energy consumption device. The hydraulic system comprises a hydraulic cylinder, a piston and a piston rod, a first though hole is formed on the piston, and the first hydraulic chamber is communicated with the second hydraulic chamber via the first through hole. An upper top plate passes through the piston rod and the piston from the transmission portion and is connected to the vibration energy consumption device to drive the vibration energy consumption device to move relative to the piston and adjust the effective aperture of the first through hole.
