摘要

针对非线性隔振原理设计出硬特性非线性混沌隔振实验装置，对以钢板、橡胶材料为隔振元件的非线性隔振系统进行了实验研究，实验得到了该装置的力学性能参数。通过数值计算得到了该装置的动力学行为。计算结果表明该装置从周期分岔逐渐进入混沌状态，线谱也从单一频谱结构变为宽频谱结构，且在混沌区域内对线谱有明显的隔离效果。

Abstract

Based on the principles of nonlinear vibration isolation, the hardening nolinear vibration isolation device was designed, which carries out the experimental study for a nonlinear vibration isolation system with a kind of steel, rubber as the isolating element to obtain the system’s chaotic characteristic parameter range. The mechanical properties of the device parameters were obtained by experiment. And obtained by numerical calculation of the dynamic behavior of the device model. The result shows that the bechvior of the device from the period bifurcation into chaotic state gradually, Line spectrum from a single spectral structure into a broadband spectral structure, and the chaotic vibration isolation’s insulation performance is preferable for line spectra isolation.
