The quasi-zero-stiffness vibration isolator is composed of a lifting mechanism and a quasi-zero-stiffness mechanism, the lifting mechanism supports a lifting plate with two rhombic mechanisms, the movement track of the lifting plate is restrained through four guide rods, the two rhombic mechanisms on the two sides are connected through four through rods, and the two rhombic mechanisms on the two sides are connected through four through rods. The two ends of the quasi-zero stiffness mechanism are connected with the through rods located on the left side and the right side in the lifting mechanism correspondingly, when vibration occurs, the two rhombic mechanisms deform in advance, the quasi-zero stiffness mechanism outputs quasi-zero stiffness, deformation of the two rhombic mechanisms can be restrained, then lifting motion of the lifting plate is restrained, and vibration isolation of an object placed on the lifting plate is achieved. In addition, the vibration isolator can conduct low-frequency vibration isolation and has the advantages of being high in static state and low in dynamic state.

    本发明公开了一种准零刚度隔振器,由升降机构和准零刚度机构构成,其中,升降机构以两个菱形机构作为升降板的支撑,通过四个导杆约束升降板的运动轨迹,两侧两个菱形机构通过四个通杆进行连接,准零刚度机构的两端分别与升降机构中位于左右两侧的通杆连接,当发生振动时,两个菱形机构预发生形变,而准零刚度机构输出准零刚度,可抑制两个菱形机构的形变,进而抑制升降板的升降运动,从而实现放置在升降板上方的物品隔振。此外,该隔振器还可以进行低频隔振,具有高静态低动态的优点。
