调谐液体惯容阻尼器减震力学模型分析及试验研究
Mechanical model analysis and experimental study on tuned liquid inerter damper
摘要
Abstract
The traditional tuned liquid damper(TLD)has the shortcomings of large water consumption,small effective damping and low damping efficiency.In order to achieve lightweight design and improve the damping ratio and damping performance,it was proposed to combine the rack and pinion inertia device with TLD to form a new type of tuned liquid inertia damper(TLID)based on inertia device.The theoretical mechanical model of TLID was established,its damping mechanism was analyzed,and a simple method was proposed to accurately calculate the total equivalent damping ratio of TLID,and the performance evaluation parameters based on time domain and frequency domain and the optimal design process of TLID were also proposed.Shaking table tests and theoretical analyses show that arranging the inertia device in the TLD can strengthen the liquid shaking in the tank,increase its apparent mass and actual damping value,and achieve better vibration damping effect;under a smaller liquid mass ratio,the vibration damping performance of TLID is better than that of the traditional TLD;under the same performance target conditions,the tunable mass ratio required by TLID can be reduced by up to 45.5％,which can achieve the goal of lightweight and efficient structural vibration damping control compared with that of the traditional TLD.关键词
