Hinge type vibration isolation device with adjustable rigidity
According to the hinge type vibration isolation device with the adjustable rigidity, the multiple hinge mechanisms which are alternately arranged up and down are arranged between the upper connecting plate and the lower connecting plate, and the elastic assemblies are installed between every two adjacent hinge mechanisms, so that the vibration isolation effect is achieved; the locking rods are installed at the bottom end of the upper connecting plate and the top end of the lower connecting plate, the span of the hinge mechanism can be adjusted, then the gradient of the hinge mechanism and the inclination angle of the elastic assembly are adjusted, and the overall vertical rigidity of the vibration isolation device is determined through vector synthesis of the normal tension and compression rigidity and the tangential shearing rigidity of the elastic assembly; due to the fact that the tangential shearing rigidity of the elastic assembly is far smaller than the normal tension and compression rigidity of the elastic assembly, the overall vertical rigidity of the vibration isolation device can be rapidly adjusted by adjusting the inclination angle of the elastic assembly, the vertical rigidity can be rapidly and flexibly adjusted according to different vibration isolation objects and vibration source frequencies, and the optimal vibration isolation effect on environment vibration is achieved; and the adaptability of a vibration isolation support product to different working conditions is improved.
本发明提供了一种刚度可调的合页式隔振装置，通过在上连接板和下连接板之间布置若干个上下交替设置的合页机构，并在每两个相邻的合页机构之间安装弹性组件来实现隔振效果，并且在上连接板的底端和下连接板的顶端安装锁定杆，可调节合页机构的跨度，进而实现对合页机构坡度的调节和弹性组件倾斜角度的调节，而隔振装置整体竖向刚度由弹性组件的法向拉压刚度和切向剪切刚度二者矢量合成而确定，由于弹性组件切向剪切刚度远小于其法向拉压刚度，调节弹性组件的倾斜角度就决定了对隔振装置整体竖向刚度的快速调节，其能够根据不同隔振对象和振源频率快速、灵活地调整竖向刚度，实现对环境振动的最优隔振效果，提高隔振支座产品面对不同工况的适应性。
