摘要

依据拉格朗日方程推导出了高层结构设置TMD减震阻尼器系统的运动方程,并根据龙格库塔法运用MATLAB编程求解。结果表明,设置TMD阻尼器以后,结构的位移、速度、弯矩等都有明显减小。该减震系统具有良好的减震性能,特别是当,M/m=1,μ=0.01,K0=104kN/m,C0=105kN/m.s时,减震效果最佳。
A theoretical analyzing approach about a novel tuned mass damper system,on high-rise building,was derived according to Lagrange Equation.The solution was programmed with MTALAB software based on the Longe-Kuta method.Computation results show that the displacement,the velocity,and the moment of the highest point were significantly decreased with this system.The system will exhibit the best efficiency with the slip friction factor being 0.01,the spring coefficient 10000kN/m,the damping coefficient 100000 kN/m·s and the tuned mass 1.0 times of the mass of per length of the structure.
