摘　　要：在提高凝汽器热效率和设备日趋大型化的同时,流体的诱导振动问题更加凸现出来,由于流体诱导振动是涉及多个领域的复杂学科,目前该难题还未得到很好的解决。基于该问题的研究现状,着重从理论上探讨了管束振动的校核方法,制作并形成了管束振动校核体系,利用相应的可视化界面程序,可直接应用于凝汽器管束的工程设计,并为工程设计中管束的防振提供理论依据。Along with the increasing thermal efficiency of condenser and tendency of large-scaling equipment, the issue of flow induced vibration has become more highlighted. For the subject of flow induced vibration is highly interdisciplinary and involves knowledge of many fields, the problem has not been solved uptil now. Based on the related research status, the checking method for tube bundle vibration is theoretically discussed in the paper, a bundle checking system is set up, a related visual interface program is directly applied to the engineering design of tube bundles for condenser and a theoretical basis is provided on hn-a, ＊ t.^ t
