Vibration Simulating and Measuring of Pipe Being Filled with Hydrogen in Chemical Ship

Abstract:

The pipe vibration’s mathematical model is established with help of the finite element impedance method, through the beam element simulating the pipeline structure, a finite element model of pipe system is constructed by means of CAESAR Ⅱ software, the vibration simulation and field testing is carried on in the abnormal vibration pipe joints, hangers and other parts, the simulation results and the field test results are compared, and then putting forward the damping project of the hydrogenation piping, the project is used in damping improving of the original hydrogenation piping, vibration test results indicate that the damping effect is obvious in the improved pipe joints, hangers supporting structure.
