中文摘要：
为了研究桥梁结构多重调谐质量阻尼器（MTMD）被动控制的特点及减振效果，根据能量守恒原理推导出了地震作用下桥梁结构动能、阻尼耗能、应变能和地震输入能的增量表达式，并用Visual C＋＋6．0语言编制了能量时程分析程序。基于桥梁的能量时程分析，从地震能量输入、地震能量分配与耗散2个方面阐述了MTMD的制振机理。最后通过MTMD振动台模拟试验验证了计算结果和制振机理分析的正确性。
英文摘要：
In order to study the characteristics and shock absorption effect of MTMD passive control on bridge structure, authors derived the numerical solution of energy equation for multiple degree structure that could provide the kinetic energy, damp dissipation, strain energy and seismic input energy under seismic effect. The energy time history analysis program was compiled with Visual C＋＋6. 0 computer language. Based on energy time history analysis, MTMD passive control mechanism was analyzed from seismic energy input and assignment. Through simulated test of MTMD shaking table, correctnesses of the calculated result and seismic control mechanism analysis were verified.
