摘要：

This paper proposes a new matrix method for calculating critical now velocity of curved pipes conveying fluid, which have arbitrary centerline shape and spring supports. Its main advantage over other methods is that the corresponding characteristic equation can be reduced to a third order one, no matter how many elements are discretized in calculation. This will lead to saving computer time and obtaining a solution with good precision. (C) 2002 Elsevier Science Ltd.
