摘要
根据所建立的磁耦合调谐质量阻尼系统的力学模型,研究了在简谐激励下磁耦合调谐质量阻尼器的运动方程,并对其进行无量纲化处理;利用数值计算分析了系统各个无量纲参数的敏感性,并对参数进行了优化处理.与传统的调谐质量阻尼器(TMD)的减振效果比较,发现磁耦合调谐质量阻尼器不但减震效果比普通的TMD好,而且磁耦合TMD自由移动的空间也大大减小,从而避免了在TMD自由运动空间受限时发生碰撞的情况.
According to the mechanics model of tuned mass damper（TMD） with magnetic coupling built,the kinematic equations of the system under the harmonic oscillation were studied and the dimensionless equations of three-degree system were derived in present study by dimensionless treatment.the sensitivity of the systemic couple parameters was analyzed by making use of numerical simulation.The effectiveness of vibration control of the TMD with magnetic coupling was studied.The research shows that the effect of vibration control of TMD with magnetic coupling is better than that of traditional TMD,and the sports space of TMD with magnetic coupling is decreased simultaneously,so that the impact between the TMD and structure can,a certain extent,be avoided.
