MATLAB在管道振动速度限值计算中的应用

Application of MATLAB in Pipeline Vibration Velocity Limit Calculation

管道振动的评价方法与旋转机械不同,分别介绍了美国ASME与法国EDF关于管道振动速度限值的计算方法。两种方法在管道振动允许速度峰值的计算中,都需要进行繁琐的计算过程,给实际工程应用中产生了一定困难。此文利用MATLAB软件编制了计算管道振动许用速度限值的计算程序,将各个标准的计算方法融合在一个界面上,并且通过选择和输入管道的相关参数,计算许用速度限值,使得管道振动的评定工作变得快速方便,便于进行管道振动的评估。

The evaluation method of pipeline vibration is different from that of rotating machinery.In this paper,calculationmethods of the pipeline vibration velocity limits by American ASME and French EDF are introduced respectively.In thecalculation of allowable velocity peak of pipeline vibration,both methods need complicated calculation process,which bringssome difficulties to practical engineering application.In this paper,MATLAB software is used to compile the calculation programof allowable velocity limit of pipeline vibration.The standard calculation methods are integrated on same interface.With selectedand input relevant parameters of pipeline,allowable velocity limit is calculated,which makes the evaluation of pipelinevibration quick and convenient and provides help for evaluation.
