The invention relates to an active adjustable vibration isolation system which comprises a high-pressure chamber, a low-pressure chamber, an electromagnetic valve, a pressure sensor, a damper, a piston rod, a cylinder barrel and a height sensor. A fixed partition plate is arranged in the cylinder barrel, and an oil through hole is formed in the partition plate; the piston rod is arranged in the cylinder barrel, the damper is connected to the lower side of the piston rod, the inside of the cylinder barrel is divided into three cavities by the partition plate and a piston, the three cavities sequentially include a compressed air cavity a, a middle oil cavity b and a lower air cavity c, air is filled in the upper portion of the compressed air cavity a, and oil is filled in the lower portion of the compressed air cavity a. The active adjustable vibration isolation system has the advantages that the system comprises the height sensor and the pressure sensor, the height sensor detects change of the distance from the cylinder barrel to a lifting lug, and the pressure sensor detects change of the pressure of the compressed air cavity a; the damper and a spring which are connected with the cylinder barrel realize an impact relief effect, so that a carried mass at the upper end of the cylinder barrel can assuredly translate in a vibration-sense-free manner; when the vibration-sense-free translation vibration isolation system is applied to a suspension of an automobile, the vibration-sense-free translation vibration isolation system can realize effects of attenuating vibration and keeping an automobile body stable, and the height of the automobile body also can be adjusted.
