压力波在可变形薄壁水管中的传播

本文从流体弹性力学的基本观点出发,考虑到管壁变形时的影响,导出了压力波在弹性薄壁水管中传播问题的偏微分方程组,在简谐载荷下求得了线性情况的解析解,并探讨了非线性方程求解析解的可能性,同时将之与刚性管的情况作了比较。

Propagation of Compressive Waves along Water Pipe with Deformable Thin Wall

This paper derives the partial differential equation system of the propagation of compressive waves along a water pipe with elastic thin wall based on the hydro-elastic mechanics in which the wall deformation is considered. The analytical solution of the linear case under the condition of harmonic loading is given. The possibility of obtaining analytical solution for non-linear equations is also discussed. The results are compared with the case of a rigid pipe.
