(華中科技大學土木工程與力學學院，武漢430074)［摘要］根據(jù)Fujino等提出的矩形TLD減振基本原理，建立了TLD中液體動水壓力的控制方程，并采用有限差分法對矩形淺水TLD液體動水壓力進行數(shù)值模擬。通過對某四層鋼架多自由度結(jié)構(gòu)體系在有TLD與無TLD的情況下分別進行模擬的計算結(jié)果比較可知，即使多自由度結(jié)構(gòu)體系振型比較復雜， TLD對其仍具有比較好的減振作用，數(shù)值模擬結(jié)果與試驗研究相符。［關(guān)鍵詞］TLD；數(shù)值模擬；動水壓力；有限差分法；滯回曲線Numerical simulation of dynamic response of tuned liquid damperChen Zhaoping，Dong Ping(Huazhong University of Science and Technology，Wuhan 430074，China)Abstract:The governing equation of the water movement in the TLD based on the basic principle of the vibration suppression of the structure with shallow water TLD presented by Fujino,is derived. The finite difference method is used to simulate the dynamic liquid pressure. By comparing the results of the simulated response of the multi-degree of freedom structure with TLD and without TLD, it concludes that the TLD system can control the vibration of the structure effectively and the TLD system can be better used to the tall buildings.Keywords:TLD; numerical simulation; dynamic liquid pressure; finite difference method; hysteretic curve作者簡介：陳招平，碩士研究生，一級注冊結(jié)構(gòu)工程師，Email:zaopin008.student@sina.com。
