摘要
提出了3种平面内自由运动的调谐质量阻尼器(TMD)构造形式,即十字形(CTMD)、X形(XTMD)和旋风形(TTMD),通过有限元模型对比分析了3种TMD刚度变化、模态和简谐激励振动响应。根据分析结果可知,当TMD激励方向与弹簧垂直时,弹簧出力表现出非线性行为;相比于其他构造形式,TTMD减振效果更为稳定,效率更高。当质量比大于3%时,TTMD抑振效果更为显著。
This paper proposes three types of tuned mass damper(TMD),i.e.,cross shaped mass damper(CTMD),X shaped mass damper(XTMD),and tourbillion shaped mass damper(TTMD)with free motion in the plane.The stiffness changes,modal,and vibration responses under harmonic excitation of the three TMDs are compared and analyzed using the finite element model.The analysis results indicate that when the excitation direction of a TMD is perpendicular to the spring,the spring force exhibits a nonlinear behavior,and compared with other TMDs,TTMD has a better robustness and higher utilization efficiency.When the mass ratio is greater than 3%,the vibration suppression of TTMD is more significant.
