Research on Quasi-zero Stiffness Vibration Isolation Technology of Distribution Transformer

Based on the traditional linear vibration isolation system, the inclined spring is incorporated as a negative stiffness element, and the positive and negative stiffness cancel each other to achieve a quasi-zero stiffness (QZS) state. The low-frequency diaphragm performance of the quasi-zero stiffness diaphragm is verified by numerical simulation analysis and dynamic simulation. The theory model the zero stiffness structure, compare the quasi-zero stiffness structure, the bearing capacity, structure complexity, cost, service life and adjustable structure, the common linear vibration absorber, and establish a simulation model through Adams, the simulation results show that the quasi-zero stiffness isolator has better vibration isolation performance than the linear vibration isolator of the same size.
