The concept of quasi-zero-stiffness (QZS) vibration isolator was proposed in recent decades to improve the low-frequency isolation performance without increasing the static displacement. This work is devoted to the concrete realization of a QZS isolator by utilizing transverse groove springs. Firstly, the QZS isolator is theoretically analyzed and some dynamical indices are analytically calculated. Then, the transverse groove springs are designed and the isolator prototype is assembled; the QZS feature of the prototype is basically fulfilled. Finally, the experiments are conducted by means of an electrodynamic shaker which generates sinusoidal base excitation for the isolator prototype; the experimental results clearly show the good isolation performance of the QZS isolator and meanwhile reflect some practical factors that should be noticed in actual applications.

带有横向槽弹簧的准零刚度隔振器的设计与试验研究

近几十年来，人们提出了准零刚度（QZS）隔振器的概念，以在不增加静态位移的情况下改善低频隔离性能。这项工作致力于利用横向槽弹簧来具体实现QZS隔离器。首先，对QZS隔离器进行了理论分析，并计算了一些动力学指标。然后，设计横向槽弹簧并组装隔离器原型。原型的QZS功能已基本实现。最后，实验是通过电动振动器进行的，该振动器为隔离器原型产生正弦基极激励。
