TESTING DEVICE FOR QUASI-ZERO STIFFNESS VIBRATION ISOLATOR

摘要

Disclosed is a testing device for a quasi-zero stiffness vibration isolator. The testing device comprises a negative stiffness adjusting mechanism (1), a positive stiffness adjusting mechanism (2), and a beam-damping block mechanism (3). The negative stiffness adjusting mechanism (1) and the positive stiffness adjusting mechanism (2) are sequentially connected, and are mounted on the beam-damping block mechanism (3). According to the device, the smooth and steady longitudinal vibration of a tested system can be achieved, and a positive stiffness value and a negative stiffness value of the overall mechanism can be flexibly adjusted. The testing device is suitable for a vibration model test of a quasi-zero stiffness vibration isolator, and problems such as that the existing quasi-zero stiffness vibration isolator device has a complicated usage method which is incapable of flexibly adjusting the stiffness of the overall mechanism, and that the process of replacing a stiffness element is complicated are solved.
