Highly Integrated Self-Sensing Six-Axis Conical Vibration Isolator

Abstract

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.

Description

technical field [0001] The invention relates to a vibration isolator, in particular to a highly integrated self-induction six-axis conical vibration isolator. Background technique [0002] A vibration isolator is a vibration isolation device installed between the base and the load to be isolated, usually containing stiffness elements (springs), damping elements (dampers) and actuators (such as piezoelectric actuators) , by changing the dynamic characteristics of the system to isolate the vibration transmitted from the base to the vibration-isolated load, thereby improving the vibration environment of the vibration-isolated load. [0003] According to the type of actuating device selected, vibration isolators can be divided into three categories: passive vibration isolators, active vibration isolators, and semi-active vibration isolators. However, it is also possible to mix passive and active isolation principles to form a hybrid isolation. Passive vibration isolators usual...
