| Abstract: | By using simulation software LS-DYNA,a 2-D finite element model was built up and the slamming of trimaran cross structure was studied.In the study many factors affecting the slamming pressure peak value of trimaran cross structure were considered.These factors are air cushion,structure mass,width of cross structure and degree of main hull deadrise.From analyses,the rules that these factors affect slamming pressure peak value are established. |
