Dynamical strength and design optimization of pipe-joint system under pressure impact load

Abstract

This article is focused on the dynamical strength analysis and design optimization of a pipe-joint system. A three-dimensional model of a fuel pipe-joint system is established and the strength and dynamic analysis of the system under the pressure impact load is analysed. In order to avoid dangerous forced vibrations or resonance, and to lower vibration level, the clamps’ numbers and locations are optimized. The results show that: (a) under the pressure impact load, near the T-branch pipe, clamps and elbows, the pipe system’s failure can easily occur; and (2) the numbers and locations of clamps of pipe-joint system can be optimized and the optimized pipe-joint system has better anti-vibration ability.
