Intelligent vibration isolator and damping and rigidity adjusting method thereof
The invention discloses an intelligent vibration isolator and a damping and rigidity adjusting method thereof. The intelligent vibration isolator comprises a top plate, a bottom plate, a damping adjusting mechanism, a plurality of rigidity adjusting mechanisms, an acceleration sensor, a signal processor and a central processing unit. The other end of the damping adjusting mechanism is connected with the bottom plate; the multiple rigidity adjusting mechanisms are located between the top plate and the bottom plate. The acceleration sensor detects vibration information during external disturbance in real time, and the signal processor carries out frequency domain analysis and vibration level evaluation on the vibration information. When adjustment is needed, the central processing unit adjusts the damping adjusting mechanism and the rigidity adjusting mechanism according to the pre-stored optimal damping adjusting position, the pre-stored optimal rigidity adjusting position, the pre-stored frequency domain analysis result and the pre-stored vibration level evaluation result. While damping and rigidity can be achieved, automatic adjustment is achieved, the effective vibration isolation frequency of the vibration isolator is changed, and the vibration isolation frequency band is widened.
本发明公开了一种智能隔振器及其阻尼和刚度调节方法，所述智能隔振器包括顶板和底板、阻尼调节机构、多个刚度调节机构、加速度传感器、信号处理器以及中央处理器；阻尼调节机构的一端与顶板连接，另一端与底板连接；多个刚度调节机构位于顶板与底板之间；加速度传感器实时检测外部激扰时的振动信息，信号处理器对振动信息进行频域分析和振级评估，在需要进行调节时由中央处理器根据预先存储的最优阻尼调节位置和最优刚度调节位置、频域分析结果和振级评估结果对阻尼调节机构和刚度调节机构进行调节。本发明可实现阻尼和刚度的同时、自主调节，改变了隔振器的有效隔振频率，拓宽了隔振频带。
