Abstract

The invention discloses a ship body inertia load testing method based on a model test, and relates to the field of ship structure safety, and the method comprises the steps: installing an acceleration sensor at a designated part of a segmented reduced scale ship body model for measuring an inertia load time domain signal; carrying out a pool test on the segmented reduced scale hull model to obtain an actual ship scale inertia load transfer function under different wave conditions, the wave conditions including different wave direction angles and different circular frequencies; based on a real ship scale inertial load transfer function, a corresponding extreme value is calculated to be an inertial load design value when an override probability that an inertial load exceeds a certain extreme value is a certain value, and a certain guiding significance can be provided in a ship design stage.
