摘要
本文根据实测得到的国产300MW锅炉燃烧压力场功率谱密度函数,研究了用计算方法估计由燃烧诱发的结构振动,并与用实测方法获得的振动值作了对比,结果很接近。从而证明计算所用的数据与方法是可靠的。
This article introduces a calculating method to estimate the vibration displacement of boiler structure caused by combustion. The Calculation is based on the power spectral density function of burning pressure field, obtained in home-made 300 MW boilers.A comparison is made between the calculating value and the measuring value of the vibration displacement. The former is in close agreement with the latter, It shows that the calculating data and methed are both reliable.
