Abstract：The paper proposes an adaptive quasi-zero stiffness vibration isolation system with multiple plate interlocking disc springs and helical springs in parallel to address the issue of non-adjustable performance ofquasi-zero vibration isolation systems according to load.The study involves the analysis of physical characteristics and mathematical models of positive and negative stiffness elements，exploration of low-frequency vibration isolation characteristics and feasible design parameters，dynamic response analysis under swept frequency signal excitation，comparison and analysis of vibration isolation performance，as well as verification through simulation.The results demonstrate thatthe proposed system canadapt to changes in load by adjusting the pretension of the coil spring，thus resulting in significantly higher low-frequency vibration isolation effect compared to non-adjustable zero-stiffness systems.This research provides theoretical guidance for designing quasi-zero stiffness vibration isolation systems.

为解决线性隔振系统高静态承载能力与低起始隔振频率之间的固有矛盾以及负载变化会削弱隔振系统隔振性能等问题，准零刚度（quasi-zero stiffness，QZS）隔振系统已成为研究的热点。（剩余14196字）
