摘　　要：针对列管式换热器的导流管工作失效问题,根据GB151和JB4732标准的相关规定和计算方法,结合有限元软件对端板-导流管-折流板典型结构的仿真结果,形成了一套适用于管程式换热器的计算方法。研究表明,通过该方法计算得到的结果与试验结果基本一致,两者误差<5%,可见利用该方法能有效进行列管结构的稳定性分析,为产品的研制生产提供保障。According to the relevant regulations and calculation methods of GB151 and JB4732 standards,a set of calculation methods applicable to tube heat exchanger is formed by combining the simulation results of the typical structure of end plate-guide tube-folded plate by finite element software.The study shows that the results obtained by the method are basically consistent with the test results,with an error of<5%between the two.
