| 摘 要： | 目的研究非线性隔振系统的动力学行为。方法以立方非线性系统为研究对象,研究了阻尼系数?、无量纲参数R对放大倍数的影响规律,并进行了隔振设计。结果随着阻尼系数?和无量纲参数R的增大,放大倍数峰值减小。结论系统的非线性行为有利于系统隔振性能,即便阻尼系数等于0的情况下,也不会出现放大倍数无穷大的情况;系统阻尼的增加,有利于改善隔振性能。

| Abstract: | The paper aims to study the dynamic behavior of the nonlinear vibration isolation system. Influences of damping coefficient and dimensionless parameter R on the magnification of the cubic nonlinear system were studied, and the isolation design was carried out. The magnification peak decreased with the increase of damping coefficient and dimensionless parameter R. The nonlinear behavior of the system was conducive to the isolation performance of the system. Even if the damping coefficient equals zero, there will be no infinite magnification; the increase of the system damping is conducive to the improvement of the isolation performance. |
