Abstract

The invention discloses a vibration isolation device. The invention comprises a working platform and a supporting platform, a plurality of magnetostrictive actuators are arranged between the working platform and the supporting platform, an acceleration sensor is arranged on the working platform. The acceleration sensor detects the vibration signal of the working platform, and transmits the signal to the control module, and the control module controls the actuation of the magnetostrictive actuator according to the signal, to balance out the vibration of the working platform. Rubber dampers are used to connect the magnetostrictive actuators and the supporting platform. A cooling device is arranged on the magnetostrictive actuators. The vibration isolation capability is high, and the vibration isolation effect is good.

Description

technical field [0001] The invention relates to a vibration isolation technology, in particular to a vibration isolation device. Background technique [0002] With the advancement and development of science, high-precision equipment and instruments continue to emerge, such as laser measuring instruments, high-precision electronic equipment, ultra-high-precision CNC processing machine tools, and so on. These high-precision instruments and equipment have high precision and have extremely strict requirements on ambient temperature and vibration. In order to ensure the normal operation of high-precision equipment and give full play to its high-precision characteristics, it is very necessary to take effective vibration isolation measures. The quality of vibration isolation directly affects the performance of high-precision equipment. [0003] The vibration isolation method of prior art 1 is passive vibration isolation: [0004] Add elastic damping elements between the vibration...
