【摘要】 磁流变阻尼器是一种性能优良的智能阻尼器,将其应用于实际工程中具有广阔的前景。但目前对其在结构中的优化设计研究还不够多。提出一种用于中底层建筑MR半主动控制阻尼器优化设计的方法,它是以控制结构的第一振型反应为目标,可以兼顾安全和经济两方面的要求,且设计过程较为简便。仿真计算表明,对比以往所采用的试算法,这种方法在控制的有效性和可行性方面都有明显提高。更多还原

【Abstract】 MR Damper is a well-performed smart damper with well performance, and its application in practical engineering projects has extensive prospect. At present, research on its applications in the optimum design of structures is not enough. In this paper, a method of the optimum design for a semi-active structure controlled by MR damper system is presented, response of the first vibration mode of the structure is controlled by this method, and both safety and economic demands of the structure are satisfied. Also, the design procedures are simple and convenient. The results of simulation show that the method has made remarkable advancement in both feasibility and effectiveness of structural control compared with the previously used trial method.更多还原
