输液管道结构横向振动问题的粘性效应

Effect of viscosity in transverse vibration of fluid conveying pipe

针对在输液管道结构中粘性项对横向振动问题的影响是否可以忽略的问题,采用微元法建立数学模型,得出简支梁情况下的频率解,最后算例结果表明流体粘性对管道的振动频率的影响是可以忽略不计的。

Mainly discuss whether the effect of viscosity no the transverse vibration of the fluid conveying pipe can be ignored.We make math model by micro-element and give the frequency formula in the condition of fixed and pinned end.The conclusion is that the effect of viscosity no the frequency of vibration can be ignored
