係留浮体の波浪中応答解析に対するMPS法の適用性に関する研究（第二報）

Abstract

For advancing ocean development, it is important to estimate response of moored floating structures in order to ensure the safety because they are placed on severe environment for a long time. Moored floating structures show complex motion at offshore ocean. The moving particle simulation (MPS) method is suitable to simulate the non-linear phenomena and the interaction of fluid and structures. In this study a improved MPS method which has an algorithm to solve pressure oscillation of particles and attenuation of wave height has been developed. The authors examined the applicability of the two-dimensional MPS method to response analysis of moored floating structure in regular waves. The numerical results have good agreement with laboratory data in term of time histories, spectra and frequency response, and the allow ability of the improved MPS method is indicated.
