Abstract
An algorithm, LAMPS, to track the movement of the liquid gravity center is available as a means to analyze motions of liquid in a tank. Its original program lacks versatility for use in the estimating calculations because the attenuation in the liquid is inputted from experimental values. This paper describes a test with respect to the input of attenuation which has been the drawback of this algorithm, in which the attenuation is led theoretically and its practical applicability was verified from the result of existing tests. Regarding to the evaluation of attenuation, the internal attenuation of the liquid was ignored for the calculation, but the attenuation due to the sliding of the liquid on the tank wall is taken up. The attenuation was introduced for the cases of the tank wall being made of flat plates, and the tank being spherical. The result showed that the values fro both cases were equivalent in a unit order. The algorithm was applied to drop tests and spin-up tests. As a result, it was verified that this algorithm not only can be used for calculating the gravity center locations, but also wasdeveloped to a practical calculation method to calculate the liquid force exerted
