Modeling and Analysis of the Dynamic Characteristics of Pipe Supporting Hydraulic Snubber in Electric Power Plant

발전소 배관지지용 유압완충기의 동특성 모델링 해석

This paper presents the modeling and analysis of dynamic characteristics of hydraulic snubber in electric power plant. The nonlinear state equations of 9th order to describe the dynamics of the snubber was established by Sirnulink. The simulation results show that the hydraulic snubber reacts as like the conventional shock absolvers to the high pulse shock load. The snubber also shows the peculiar characteristics to the small step load, which are temporary locking displacements of control valves and same steady-state pressures of all internal chambers in the snubber.
