摘要
结合斜拉索振动与混杂系统特点,推导并建立斜拉索振动控制系统的MLD模型。以琼州海峡大桥中几根典型斜拉索为研究对象,利用所建立的MLD模型,对阻尼器安装在3种不同位置时的风振控制参数进行分析,研究斜拉索和阻尼器的相应变化。对建立的控制系统与传统半主动控制分段线性控制系统之间的计算效率进行对比,并分析原因。
In combination with the features of vibration of stayed cables and hybrid system, this paperderives and establishes MLD model of control system for vibration of stayed cables. With a few stayed cables in Qiongzhou Strait Bridge as the objects of research, the paper analyzes control parameters of windvibration when dampers are installed at 3 different positions by means of the established MLD model, studies corresponding changes of stayed cables and dampers. The paper compares computational efficiencybetween the established control system and conventional semi - active control sectional linear control system and analyzes reasons.
