The Influence of Corrosion on the Vibration Modes of a Pressurized Fuel Tank Used in Automotive Industry

Abstract

The effect of corrosion on the frequency vibrational modes of a pressurized cylindrical fuel tank with ellipsoidal head caps was investigated in this paper. The frequency variation laws were determined by a polynomial interpolation. This method is simple, flexible and has efficient advantages, and it can shorten the optimal design of cylindrical pressurized fuel tanks with ellipsoidal head caps.
