Abstract

The invention discloses a rigidity and damping adjustable semi-active vibration isolation system. The rigidity and damping adjustable semi-active vibration isolation system comprises vibration sensors, elastic elements, a damping element, a rigidity adjusting mechanism, a damping adjusting mechanism and a controller, wherein the vibration sensors are suede for measuring vibration information of aneffective load and / or a supporting body; one ends of the elastic elements are connected with the effective load, and the other ends of the elastic elements is connected with the supporting body; oneend of the damping element is connected with the effective load, and the other end of the damping element is connected with the supporting body; the rigidity adjusting mechanism is used for adjustingthe rigidity of the elastic elements; the damping adjusting mechanism is used for adjusting the damping of the damping element; the controller is used for receiving signals of the vibration sensors and transmitting adjustment signals to the rigidity adjusting mechanism or the damping adjusting mechanism. The rigidity of the elastic elements is adjusted through the rigidity adjusting mechanism andthe damping of the damping element is adjusted through the damping adjusting mechanism to achieve vibration isolation. The rigidity and damping of the semi-active vibration isolation system can be changed through less energy in real time to achieve the effect of approaching an active vibration isolation system. Moreover, the problem of control instability is avoided to some extent.

Description

technical field [0001] The invention relates to the technical field of vibration and noise control, in particular to a semi-active vibration isolation system with adjustable stiffness and damping. Background technique [0002] According to different vibration reduction objects, vibration isolation can be divided into negative vibration isolation and active vibration isolation; among them, negative vibration isolation is to isolate the vibration of the carrier from being transmitted to the equipment, and active vibration isolation is to isolate the vibration generated by the equipment itself from being transmitted to the carrier. Generally, the vibration isolation system can be divided into passive vibration isolation system, active vibration isolation system and semi-active vibration isolation system according to whether a control unit is used. Passive vibration isolation systems usually use certain elastic and damping elements to achieve vibration isolation. Since there is ...
