弹性支承输液管道的临界流速

Critical Flow Velocity of Pipes Coneying Fluid with Elastic Supp orts

建立了求解输液管道临界流速的新方法 ,该方法把奇异函数与傅立叶级数相结合 ,将此问题转换成的实矩阵的二次特征值问题。本方法可用于任意弹性支承的输液管道 。

A new method is proposed to calculate the critical fl ow velocity of pipes conveying fluid. The problem of buckling is transformed into the matrix eigen-problem using a method combining singularity functions with F ourier series. This method can be used for pipes with variant elastic supports o n ends and/or in a middle position.
