输送流体管道振动Housner方程的修正
Correction for Housne’s Equation of Bending Vibration of a Pipe Line Containing Flowing Fluid
-
摘要: 本文既考虑了流体速度对管道的诱发振动,又考虑了振动的管道对流体的反馈影响,推出输送流体管道振动微分方程的准确形式,并指出Housner方程是近似的.Abstract: This paper points out that Housner's equation of bending vibration of a pipe line containing flowing fluid is approximate and makes correction to it.An exact form of the vibration equation is given.
