The prediction of floating position of human model after wearing life-jacket based on the three dimensional modeling

Recently , the manufacturers of life -jacket are very interested in the acquisition of USCG (US Coast Guard ) approval because the acquisition of USCG approval has an important role in the purchasing decision of the buyer ’ s. Be based on criterion of USCG , we studied how to predict the change of floating position of human model with life -jacket to verify the backside restore . For this , in this study , the human model and the life jacket was modeled in three dimension , the application program for prediction of floating position was developed , and plugged -in commercial program .
