For the structure dynamic part, the rigid and flexible modes are coupled and their mutual effects are considered. The resultant governing equations for the structure part are highly non-linear. In order to further improve the time integration accuracy, the governing equations were first reformulated into ordinary differential equation systems, then the Precise Integration Method (PIM)[2, 3] was used to solve these equations. The dynamics of flexible wedge was simulated by the developed numerical scheme, which showed a better accuracy for long time simulation compared with normal schemes such as Newmark method.enhttp://rightsstatements.org/vocab/InC/1.0/HydroelasticityTechnikIngenieurwissenschaftenConference Paper10.15480/882.334610.15480/882.3346Fluiddynamik und Schiffstheorie M-8Other
