Abstract
The purpose of this study is the development of the assessment tool for the wave energy converter.The target is the two body system,and one of the goals is the dynamic analysis of the system in three dimensional space and in the time domain.This paper presents the summary of the input wave setup and the dynamic analysis method for the system.The regular and irregular wave should be defined according to the Pierson-Moskowitz spectrum,JONSWAP spectrum,the measurement or simulation of the sea state where the system would be installed.The three dimensional movement equations for each parts should be defined and solved in time domain with the numerical methods.The simulation for the regular wave and irregular wave was carried out.
