Due to the harsh conditions high speed planing crafts must endure, research to further the understanding of high speed vessel response during wave impacts was conducted. The integration of a finite element model and captured sea trial acceleration data was investigated. The research shows that the finite element model sub-model can be used in lieu of a full finite element model with minimum degradation in output, thus allowing for the analysis of local stress concentrations where critical equipment and or personnel may be located.
The research effort was completed to develop a method for realizing the stress field and deformation generated following a wave impact. Application of base excitation was investigated and allowed for multiple studies to be completed. Validation of the method was accomplished through comparison of sea trial data with MSC NASTRAN transient response output in the form of acceleration. The method provides insight into the effect that wave impacts have on small vessels at sea, specifically the 11-meter cabin RIB, hull 11MRIB0503.
