“…Bae J H [8] has doing the preform design of fuel pipe to preventing the head of high-pressure fuel pipe from folding in the heading process. In his study, the angle, curvature and outer diameter of the die and the length of the trapped part were selected as main parameters in the design of the optimal preform shape that minimizes the radius of folding.…”

Abstract. High-pressure fuel pipe is an important component of the fuel injection system of diesel engine, it suffer complex loading from engine. The fatigue life of fuel pipe has great impact on reliability of engine. In this study, the fluid-solid coupling model which considers the action of fuel is established. Analysis on the effect of fuel's pressure oscillation on the mode is carried out. Through the simulation comparisons, the mode frequency and mode shape of each model are all analysed. Base on the fluid-solid coupling model, frequency response analysis is done to study the reliability of high-pressure fuel pipe. The results show that the pressure oscillation of fuel has important influence on the mode frequency. The maximum Stress Tensor and Vibration Velocity appeared at the position of first order mode frequency. It offers the guidance for the design and analysis of High-pressure fuel pipe.
