【摘要】 提出了一种分析输液曲管临界流速的方法 .与其它方法相比 ,该方法不但容易处理带任意多个中间支承和变刚度、变曲率的输液曲管问题 ,而且由于对各段位移、内力关系导出了一系列显式 ,故不管离散段数多少 ,最终都只需解一个三阶矩阵方程 ,因此计算量小、精度高更多还原

【Abstract】 A new matrix method is proposed for calculating the critical velocity of curved pipes conveying fluid, which have arbitrary centerline shape and spring supports. The difference between the present method and that in the literature is that the corresponding characteristic equation in the former can be reduced to a third order one, no matter how many the discretized elements may be in calculation. This will save computer time.更多还原
