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
為了解決八零三電廠2號汽輪機四根主蒸汽導汽管道振動的問題，本文建立了相應的計算模型，並根據計算和實測結果，找出了振動的主要原因，提出了加裝偏轉支吊架和管道並聯的改進措施，完成了改造工作。本文主要工作是：建立導汽管計算模型，並應用ansys5 . 6有限元分析軟體，對機組四根導汽管治理前的10階固有頻率和前8階振型進行計算。 -
( 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
通過現場勘察，根據計算和測量結果，決定在不改變導汽管原有設計和布置，同時又滿足國家標準的前提下，採用加裝偏轉支吊架、導汽管並聯的措施，通過改善導汽管剛度和改變管道固有特性的方法，對該機組四根導汽管振動問題進行了處理。 -
In many big enterprises such as electric power and pentrifaction ones, there are lots of high temperature and pressure pipelines conveying steam. because of improper design, collocation and adjustment of the supporting and suspending nogs, pipelines often vibrate, which affects natural life, threatens safe production and even leads to grave accident
在電力、石化等大型企業中，存在著大量的高溫、高壓輸汽管道，由於支吊架設計、布置和調整不當，管道常常發生振動，影響管道的使用壽命，對安全生產造成威脅，甚至引起重大事故。
