              摘要: 惯容减震系统是一种高效复合动力吸振装置,可对结构的多种振动指标进行控制。现有惯容系统减震设计方法主要对
              结构位移响应进行控制,不能显式发挥惯容系统多指标控制的作用。考虑到速度是体现结构振动强弱的重要指标,本文提出
              将结构位移响应和速度响应同时作为惯容减震系统的设计指标,即在满足结构位移减震需求的条件下,令结构的速度响应最
              小。推导了惯容减震结构随机振动响应的解析表达式,进而得出了惯容减震系统基于速度最小化原则的解析设计公式,并提
              出了单自由度惯容减震结构基于速度最小化原则的性能需求导向设计方法。利用减震主自由度原理将单自由度惯容减震结
              构的设计公式推广至多自由度结构。设计算例分析验证了所提设计原理与方法简便可行,能有效实现对地震作用下惯容减震
              结构位移响应和速度响应的控制,并验证了设计方法和公式的合理性与准确性。

              Abstract:  An  inerter  system  is  a  new  type  of  high-efficiency  composite  power  vibration  absorbing  device,  which  can
              comprehensively  control  multiply  vibration  indexes  of  the  structure.  The  existing  seismic  mitigation  design  methods  of  inerter
              systems mainly consider the control of structural displacement responses, which cannot explicitly play the role of inerter system
              multi-indicator control. Considering that velocity is an important indicator of the strength of structural vibration, this paper proposes
              to take the structural displacement response and velocity response as the design indexes of inerter systems at the same time: i.e.,
              under  the  condition  of  satisfying  the  demand  of  structural  displacement  damping,  the  velocity  response  of  the  structure  is
              minimized. The analytical expression of random vibration responses of a structure with the inerter system is derived, and then the
              analytical  design  formula  of  the  inerter  damped  system  based  on  the  principle  of  velocity  minimization  is  obtained,  and  the
              performance demand-oriented design method of single-degree-of-freedom (SDOF) structures with the inerter system based on the
              principle of velocity minimization is proposed. The design formulation of SDOF structures with the inerter system is generalized to
              multi-degree-of-freedom (MDOF) structures by using the principle of damping principal degrees of freedom. The design examples
              show  that  the  proposed  design  principle  and  method  are  simple  and  feasible,  effectively  realize  the  dual  control  of  displacement
              response  and  velocity  response  of  structures  with  the  inerter  system  under  seismic  action,  and  verify  the  reasonableness  and
              accuracy of the design principle and formulas.
