采用频域分析法考虑ＴＭＤ在多自由度结构中的位置，推导了具有ＭＴＭＤ的多自由度结构受控振型 广义坐标的频率响应方程，据此进行了ＭＴＭＤ的参数优化和设计．算例表明，只要ＭＴＭＤ设计正确，它 就可以有效地减小结构在地震作用下的动力响应。
Taking the position of TMD in multi-degree-of-freedom structure by frequency-domain analysis, the frequency response equation of MTMD multi-degree-of-freedom controlled structures in generalized coordinates is deduced, and the parameter optimization and design of MTMD are carried out. The example shows that as long as the MTMD is designed correctly, it can effectively reduce the dynamic response of the structure under earthquake action.
