摘要
建立了船舶与海洋平台舱内管线流体荷载与局部应力的直接计算方法 ,应用总流能量方程法计算整个管系的流体压力分布 ,应用NS方程与二模式湍流方程法计算管系局部压力分布 ,最终应用有限元分析法确定管线、支座以及接头、端头。
A procedure to calculate hydro-pressure,structural stress and supporting force for ship pipelines was developed.The global energy equation and Reynolds Average Navier-Stokes Equation with two-model turbulence equations were employed to determine the hydro-pressure distribution on pipeline and the local force on pipe's elements respectively.And then the distribution of structural stress and supporting force on pipelines can be obtained by use of FEM approach.
