摘要
建立调频液体阻尼器(Tuned Liquid Damper,TLD)数值计算模型,利用OpenFOAM二相流动网格方法进行求解,并基于试验数据验证计算方法的有效性。分析TLD减振力与固有频率和激励频率的关系。建立Simapck与OpenFOAM耦合求解方法,对TLD在风机塔架上的布置数量、布置位置和固有频率对风机塔架减振效果的影响进行研究。计算结果表明,当TLD的固有频率等于塔架一阶振动频率且TLD布置在塔架顶端时,TLD的减振效果更好。
A numerical calculation model of Tuned Liquid Damper(TLD)is established,which is solved by OpenFOAM two-phase flow grid method,and the validity of the calculation method is verified based on the experimental data.The relationship of the damping force of TLD with the natural frequency and excitation frequency is analyzed.The coupling solution method of Simapck and OpenFOAM is established.The influence of the number,location and natural frequency of TLD arrangement on the damping effect of the tower is analyzed.The calculation results show that when the natural frequency of TLD is equal to the first order vibration frequency of the tower and it is arranged at the top of the tower,the damping effect of TLD is better.
