摘　　要：摆式阻尼器广泛应用于高层建筑减振,效果明显且安全经济,是目前超高层建筑研究的热点问题。其工作原理涉及大量动力学知识,理论性强且抽象,学生难以理解和掌握。为了突破这一教学难题,该文设计了有无摆式阻尼器的对比演示模型,将模型演示与力学原理分析相结合,解释了摆式阻尼器的减振原理。该项实验设计有利于增强学生对高层建筑结构减振的兴趣,启发创新思维。[Objective]With the continuous development of the structural system in high-rise buildings,pendulum dampers have become widely used to enhance the comfort and safety of these structures.However,the complexity and abstractness of the vibration reduction principle of pendulum dampers challenge the high-quality teaching of the structural design course of high-rise buildings in colleges and universities,which presents significant obstacles to the training of innovative talents in the field of structural engineering.To achieve high-quality education and effective research,a demonstration model that clearly illustrates the damping effect of pendulum dampers needs to be established.This demonstration model will aid students in mastering relevant theories and realizing independent innovation in building structures.[Methods]Based on the existing shaking table device,a simple structural model of a high-rise building was constructed using bamboo,glue,and weights.By adjusting different excitation forces,the vibration effects were demonstrated both with and without a pendulum damper.In this study,mechanical schematic diagrams were obtained from the demonstration models,and a mechanical principle analysis was performed.Teaching was conducted in combination with the demonstration model so that the students could clearly and intuitively understand the vibration reduction principle,resonance effect,and vibration characteristics under different amplitude and frequency conditions.This approach deepened the students’understanding of relevant theories and enhanced their analytical ability.Following the teaching demonstration,the students were encouraged to independently operate the teaching experiment,repair the broken nodes,and innovate the structural model.Through this method,students’comprehension of relevant theories and understanding of structural vibration damage was improved,and students’practical ability and innovative thinking were enhanced.This research established the teaching mode that integrates model demonstration
