摘要： 当流体诱发换热器管束的振动较大时, 换热管振幅最大处会产生换热管和挡板之间的碰撞, 导致换热管产生微动磨损, 进而产生破坏。利用 AN S Y S软件对某型换热器换热管的瞬态流体激振响应进行了有限元分析, 在此基础上, 研究了换热管和挡板之间由于较大的激振响应振幅所产生的随机碰撞现象, 计算了换热管和挡板
之间随机碰撞力作用下的非线性动力响应和振动规律, 为换热器管束系统的设计提供了一定的理论参考。

Abstract: When the vibration of heat exchanger tube bundle is large induced by fluid, the collisions between the tube and baffle will take place at the maximum amplitude of the tube, which leads to tube fretting wear and damage. The transient finite element analysis of fluidinduced vibration response for a heat exchanger tube was employed with ANSYS software. On this basis, the phenomenon of random rubbing between the bezel and tube was studied due to the larger vibration amplitudes of the tube. The nonlinear dynamic response and vibration rules of the random collisions between the bezel and tube were calculated. The calculated results provide a theory of reference for the design of heat exchanger tube bundles.
