Abstract

Abstract

In view of the excessive vibration of the outlet pipeline system of marine reciprocating pump, the fluid-solid coupling analysis method was used to establish the system-level vibration transmission characteristics analysis model applicable to the outlet pipeline with the field test data, and the vibration response characteristics of the pipeline system were analyzed by using the established model. Based on the methods of modal matching and vibration node coupling, the design principles for optimal arrangement of pipeline hangers and parameters were put forward, and the sensitivity analysis of hanger types and parameters was carried out. The analysis results show that the peak vibration displacement and peak velocity of the pipeline are significantly reduced after the optimization of pipeline hanger arrangement, and the average vibration acceleration level at the base is 3.48dB lower than that before optimization.
