This study presents a Multi-layer Quasi-Zero-Stiffness (ML-QZS) vibration isolation platform for variable loads in large-amplitude and low-frequency dynamic environments. In one mount of the proposed ML-QZS platform, permanent magnets are constructed to generate discontinuous negative-stiffness regions. The first design criterion is achieve wide-amplitude range different loads. second carried out performances transient steady states. Since both structural damping determine time displacement transmissibility, which often exhibit contradictions depending on system parameters, bi-objective Pareto optimization balance transients between layers while ensuring significant effectiveness layer. Finally, relevant experimental prototype constructed, results verify principle double magnetic ring construction criterions parameters coefficients. provides an advanced nonlinear with wide QZS loads, method coordinate performances, important theoretical guidance realization platforms practical engineering applications
