Vibration Emulating and Measuring of Pipe System Being Filled with Liquid Ammonia in Chemical Ship

Abstract

Above all, it is discussed about vibration mechanism of the pipe system being filled with liquid ammonia in a chemical ship, the mathematic equations of pipe vibration are deduced, and finite element model of the pipe system is constructed by means of CAESARⅡ software, then according to constructed model, vibration emulating of the pipe system is done with the help of MATLAB software, and field measuring of vibration is also done in the connection and elbow of the pipe system, dynamic damping project is put forward after the results of emulating are compared with measuring values of vibration in a chemical ship, original pipe system being filled with liquid ammonia is improved on the basis of the dynamic damping project, in the end, vibration values of improved pipe system are tested and analyzed again, the results of testing indicate that adopted dynamic damping project is feasible.
