Abstract
To improve the efficiency and precision of measuring and adjusting the weight,center of gravity,and moment of inertia of a ship model,the principle of equilibrium of moment and the small scale principle were used to study the method of measuring the weight,center of gravity,and moment of inertia for a ship model.An integrated electrical measuring system of weight,center of gravity,and moment of inertia for a ship model was designed and developed,and the systematic error was analyzed.Standard model experiments were carried out to compare the metrical data with the inherent standard model parameters and analyze the precision and repeatability of the measuring system.Many experiments confirm that the repeatability of the measuring system is acceptable and the precision is high,meeting the demands of the ship model test in a laboratory pool.The measuring system has improved practical value.
