在高层建筑顶部悬吊质量摆是一种新型的减震形式,已经成功应用到国内外很多工程建筑结构中。主要针对单层框架结构来设计试验装置以研究悬吊质量摆的减震效果。该试验装置操作简单、减震效果形象直观,同时可以进一步研究悬吊质量摆的质量大小和摆长对减震效果的影响。通过建立悬吊质量摆的单层框架结构的动力学模型,推导出达到最佳减震效果时的质量和摆长等条件的理论公式。试验结果与理论推导的结果能够较好吻合,表明可以很好用于课堂演示教学和学生操作实验。 The pendulum mass pendulum on the top of high-rise buildings is a new form of shock absorption that has been successfully applied to many engineering structures at home and abroad. Mainly for the single-story frame structure to design test device to study the damping effect of pendulum mass pendulum. The experimental device is simple to operate and the visual effect of the damping effect is intuitive. At the same time, the quality of the pendulum mass and the influence of the pendulum length on the damping effect can be further studied. By establishing the dynamic model of single-story frame structure with suspended mass pendulum, the theoretical formula of the quality and swing length when the optimal damping effect is achieved is deduced. The experimental results are in good agreement with the theoretical ones, which shows that it can be used in classroom demonstration teaching and student operation experiment.
