摘要
旨在建立一类新型含磁准零刚度隔振器系统的力学模型。该系统通过并联具有负刚度特性的磁力弹簧和线性正刚度弹簧,使系统在小位移内具有刚度渐硬特性,较大位移内同时具有刚度渐硬和刚度渐软特性,并推导出其动力学方程。通过分析力-位移结构特性、刚度-位移结构特性,获得其实现准零刚度的条件。研究结果为实际工程应用中隔振器的设计及参数优化提供了理论参考,具有一定的实际意义。
The aim to establish a new type of mechanical model with a novel magnetic quasi-zero-stiffness isolator system. The system through the parallel connection of negative stiffness characteristics of magnetic springs and linear positive stiffness springs, the system has a rigid stiffness in the small displacement characteristics, the larger displacement at the same time has the rigidity of the stiffness and stiffness gradually softening characteristics, and its dynamics equation is derived. By analyzing the characteristics of force-displacement structure and stiffness-displacement structure, the conditions for achieving quasi-zero-stiffness are obtained. The results provide a theoretical reference for the design of vibration isolator and parameter optimization in practical engineering, which has certain practical significance.
