应用调谐质量阻尼器抑制岸桥风致振动的研究

Research on Depression of the Wind Induced Vibration of Quay Container Crane by Using Turned Mass Dumper

岸桥受风致振动会产生较大的晃动 ,不仅影响正常的装卸作业 ,也成为整机的严重安全隐患。应用调谐质量阻尼器是抑制振动的一个有效的方法。笔者首次将调谐质量阻尼器应用于岸桥的抑振研究 ,根据对岸桥受风激励所引起的整机动力特性的分析 ,设计了相应的调谐质量阻尼器 ,确定了其相关参数。计算机模拟结果表明 。

Container crane will be brought great rock by wind-induced vibration. It not only affects the normal operation, but also becomes hidden trouble of safety. Using TMD (Tuned Mass Dumper) is an effect method for restraining vibration. According to the analysis of the dynamic character of the container crane by wind stimulate, the writer study using TMD restrains wind-induced vibration of container crane, and designed the accordingly TMD and it's parameters. Though computer simutation, the result declares that restraining the container crane of wind-induced vibration had distinct effect by using the appropriate TMD
