According to results of calculations and experiments , main causes that contribute to vibration are founded , then puts forward improving measures of adding deflexed supporting and suspending nogs and making pipelines shunt - wound , finally completes improvement tasks following is the main works completed in this thesis : ( 1 ) this thesis sets up a mathematic model of steam pipelines , using ansys5 . 6 limited - unit analyzing software , calculates the ten phase inherent frequency and the foregoing eight phases vibration types of four steam pipelines of the unit before dealt with 为了解决八零三电厂2号汽轮机四根主蒸汽导汽管道振动的问题，本文建立了相应的计算模型，并根据计算和实测结果，找出了振动的主要原因，提出了加装偏转支吊架和管道并联的改进措施，完成了改造工作。本文主要工作是：建立导汽管计算模型，并应用ansys5 . 6有限元分析软件，对机组四根导汽管治理前的10阶固有频率和前8阶振型进行计算。

( 3 ) by spot reconnaissances , according to the results of calculations and measures , the problem of vibration is solved by adding deflexed supporting and suspending nogs , making pipelines shunt - wound and without changing the previous design and collocation , which can also measure up nationally . to complete the improving program successfully , the improving project is demonstrated using ansys5 . 6 limited - unit analyzing software , the results of it show that the project put forward can resolve the problem of transmitting steam pipelines 通过现场勘察，根据计算和测量结果，决定在不改变导汽管原有设计和布置，同时又满足国家标准的前提下，采用加装偏转支吊架、导汽管并联的措施，通过改善导汽管刚度和改变管道固有特性的方法，对该机组四根导汽管振动问题进行了处理。
