A highly integrated self-sensing hexa-axial conical vibration isolator relates to a semi-active vibration isolator and contains an upper end frame, an upper ball hinge seat, upper ball hinges, support leg members, lower ball hinges, a lower ball hinge seat and a conical frame; on the support leg members, a magneto-rheological damper, a die spring, a pull pressure sensor, a displacement sensor and an acceleration sensor are integrated. The vibration isolator is mounted between a base and a load subjected to vibration isolation, when the base generates vibration, the sensor integrated in the vibration isolator collects a vibration signal and feeds back to the controller, the controller performs operation and controls the size of a current that leads into the magneto-rheological damper, and a damping power size of the magneto-rheological damper is adjusted in real time, such that a vibration environment of the load subjected to vibration isolation is improved and the purpose of vibration isolation of the load subjected to vibration isolation is realized. The vibration isolator has the characteristics of high integration, multi-freedom degree vibration isolation, adjustable damping force, low power consumption, self-sensing feedback and the like, and can be widely applied to the fields where the vibration isolation is applied, such as aerospace, automobiles and ships.
