Abstract

Finite element analysis was used in this study to analyze dynamically the stability of a pipe which is stiffened by linear spring and conveying an internal flow of fluid. Several effective parameters play an important role in stabilizes the system, such as stiffness addition. The effect of stiffness addition (linear spring) and effect of spring location with different diameter ratio were studied. Also, effect of the velocity of flowing on the dynamic stability of the system was taken into the consideration. There is a spring constant at which the dynamic behavior becomes more sensitive and the spring offers best results for frequency of the system. Results show that the best spring’s locations depend on the spring’s constant and velocity of flowing.
