摘要
为了明晰颗粒阻尼器的减振性能,以铝制框架结构为研究对象,设计制作了颗粒阻尼器。通过振动台试验,研究了结构在简谐波和地震波下的振动特性,分析了阻尼器中颗粒的大小、质量等参数对颗粒阻尼器减振效果的影响。结果表明:颗粒阻尼器能够降低结构在振动时的位移;采用不同质量和不同直径球体的颗粒阻尼器对结构减振的效果有所差异。在不规则波作用下,颗粒阻尼器减振效果良好,结构顶端位移和加速度均有明显下降。
In order to clarify the damping performance of the particle damper,this paper employed the aluminum frame structure,designed and produced the particle damper.Through shaking table tests,the vibration characteristics of the structure under sinusoidal and seismic waves were studied,the influences of the particle size and mass on the vibration damping effect were analysed.The results show that the particle dampers can reduce the displacement of the structure during vibration.Dampers with different particle masses and diameters have different effects on structural vibration reduction.The particle damper achieved a good damping effect under irregular waves,and both the displacement and acceleration at the top of the structure are significantly reduced.
