| 中文摘要: |
| 研究了受均布切向荷载作用下输流管道发生静态失稳的临界流速。建立了简单的管道模型,并根据微元的受力平衡建立了整个管道系统的微分方程,利用Ritz-Galerkin对其离散化,然后无量纲化.运用MATLAB中Runge-Kutta数值积分方法对微分方程求解,并分析了切向力和质量比对管道系统的影响. |
| 英文摘要: |
| Critical flow velocity of pipe line containing flowing fluid under uniformly tangential load is studied.A simple pipeline model is established,and differential equation of the pipeline system is established on the basis of equilibrium,the equation of motion of the pipe is discreted by Ritz-Galerkin method and then dimensionless.Solving the differential equations by using the Runge-Kutta numerical method in MATLAB,and effects of the shear force and quality ratio on the pipeline system are discussed. |
