摘要
阻尼摆减震是提高高层建筑稳定性的一种有效方法。本研究在减震系统动力学分析的基础上,研究阻尼摆减震的关键因素及系统参量关系,搭建减震装置并通过实验定量评估实际减震效果和抗震能力。研究表明,无论是在周期性外力作用,还是非周期性外力作用,阻尼摆对主体振子在周期性外力和瞬时外力作用下的振动幅值减震比和振动路程减震比均达到20%,抗震能力明显提升。并通过不确定度评估了实验装置的可靠性。本文从理论到实践,从定性到定量,深入分析了阻尼摆减震的原理和装置实现,对力学知识的深入理解与应用具有教学意义。
Damping pendulum is an effective method to improve the stability of high-rise buildings.Based on the dynamic analysis of the damping system,this study investigates the key factors and system parameter relationships of damping pendulum,builds a damping device,and quantitatively evaluates the actual damping effect and seismic resistance through experiments.Research has shown that whether under periodic or non-periodic external forces,the damping pendulum has an average damping ratio of 20%on the amplitude and displacement of the main oscillator vibration,significantly improving its seismic resistance.And the reliability of the experiment was evaluated through uncertainty analysis.This article deeply analyzes the principle and device implementation of damping pendulum damping from theory to practice,from qualitative to quantitative,and has teaching significance for the deeply understanding and application of mechanical theory.
