Abstract
To investigate the liquid level response characteristics inside a built-in pressurizer under severe sea conditions,a large six-degree-of-freedom motion platform was used to test and analyze pressure fluctuation patterns caused by liquid levels during large-scale multi-degree-of-freedom violent motions(e.g.,rolling 45°/7 s).Results show that under motion excitation,the maximum measured pressure is approximately 11 000 Pa.Pressure fluctuation periods correlate with motion excitation periods,and fluctuation amplitudes are dominated by motion amplitudes in primary directions.Rolling motion affects pressure signals because the straight-line distance between the liquid surface and measurement point changes periodically during oscillation,causing periodic pressure fluctuations.Swaying and surging motions influence pressure signals as fluid periodically impacts walls,generating two-or three-dimensional standing waves on the liquid surface.Heaving motion affects pressure measurements primarily through vertical acceleration changes,periodically causing overweight and weightlessness phenomena.This study provides a basis for obtaining true liquid level values in pressurizers,avoiding unnecessary limit alarms during reactor operation,and enhancing reactor operational reliability.关键词
