摘要
本文是理论计算与工程实际相结合的典型例子．某电厂锅炉送风机，多次发生叶片断裂事故，严重影响了电厂生产的正常运行，受电厂委托，我所就风机动叶片断裂事故，采用有限元方法对转子、支承结构、壳体和动叶片均进行了一系列的计算分析，找出了故障原因，并提出了改进措施．
The present paper is a typical example which combined the theoretical calculation with the engineer practice. An axial fan of coal fired boiler fail many times, it seriously effect the running of the power plant. After a detail calculation and analysis about the rotor, bearing system, shell and blade by means of finite element method, the author find the cause of the axial fan's failure, and give a useful suggestion.
