Statistical analysis of sloshing-induced random impact pressures

Abstract

This article presents the statistical analysis of sloshing-induced random impact pressure. To obtain the pressure signal, three-dimensional sloshing model tests were conducted at two different filling depths. Several different methods were applied to identify sloshing peaks and to define the rise and decay times of the peak pressure signals. Statistical properties acquired from these methods were compared, and their consistency and/or discrepancy were observed. In addition, 200-h duration test data were acquired by running forty 5-h tests under each test condition. Based on the long-duration test data, the uncertainty of the test results with respect to the test duration was studied using the bootstrap method.
