Abstract
Corrugated pipes are flexible devices widely used to accommodate axial and lateral deflections subjected to mechanical vibrations in many industrial applications. Several researches studied the problem of such pipes when conveying fluids. Some others treated the problem on the basis of fluid structure interaction. Many researchers analyzed the problem considering the dynamic behavior of the pipes elastic structure. To the author knowledge, nothing has been done to study the effect of physical and geometrical factors upon the fundamental vibration behavior. In the present work a generalized mathematical model of a corrugated pipe, carrying a stagnant fluid, is put forward and is subjected to lateral sinusoidal exciting force. The results, of this study, indicated that corrugated pipes experience large vibration amplitudes when subjected to higher exciting frequencies. Also, it is concluded that the number of corrugations has a little effect, on the vibration amplitudes, compared with the waviness to diameter ratio of the pipe. The safe range, of pipe length to diameter ratio, is found to be 5 over a relatively wide frequency band.
