[摘要]大型焦炭塔內部物料反應引起焦炭塔塔體、支承結構、鋼框架及管線的振動。異常的振動使人產生恐慌,并影響日常生產,需采取有效的振動控制措施減小振動。以某石化企業焦炭塔為研究對象,通過動力測試、計算分析得到焦炭塔異常振動是由塔體內部物料反應和運動引起的。通過在焦炭塔塔體頂部設置TMD減振系統,對比分析焦炭塔在相同動力荷載作用下安裝TMD前后的動力響應,驗證了TMD減振系統在焦炭塔結構上起到良好的減振作用。安裝TMD后,焦炭塔減振率在50%以上,能夠保證焦炭塔日常安全生產。該焦炭塔結構TMD減振系統的應用可為類似工程的減振設計提供參考。

Abstract:The reaction of materials inside the large coke tower causes vibration of the coke tower body, support structure, steel frame and pipeline. Abnormal vibrations cause panic and affect daily production,  effective vibration control measures are needed to reduce vibration. Taking the coke tower of a petrochemical enterprise as the research object,  the abnormal vibration of the coke tower through dynamic test and calculation analysis is caused by the reaction and movement of materials inside the tower body. By setting up the TMD  on the top of the coke tower, the dynamic response of the coke tower before and after the installation of the TMD  under the same dynamic load was compared and analyzed. It was verified that the TMD damping system plays a good role in damping the coke tower structure. After the installation of TMD, vibration reduction rate of the coke tower  is above 50%, which can ensure the daily safe production of  the coke tower. The application of  TMD damping system in the coke tower structure can provide reference for vibration reduction design of similar projects.

Keywords:large coke tower; reaction of the material; dynamic load; TMD damping system
