TI  - INVESTIGATION OF BOAT MOTION ON OCCUPANT IN PATROL BOATS
AB  - Occupants in high-speed patrol boats are subject to impact forces due to various boat motions. These impact forces should be precisely calculated and accounted for when designing seats for occupants. Hull design and cruising speed are the most critical parameters that cause shock and impact on the boat during the journey. In addition, seat design and material also have a major effect on the impact level sensed by the occupant. In this study, Altair software (Hypermesh and Radioss) is used to build a sample Computer Aided Engineering (CAE) seat and occupant model for patrol boats. The occupant CAE model (50th percentile, Hybrid III) used in our study is already available in the software library and has been verified based on physical testing. During investigation, accelerations coming from reference studies are applied on the model and CAE results are investigated to understand occupant kinematics better. Different accelerations, seat foam thicknesses, and seat foam materials are tested numerically in CAE models. Based on the CAE results, strong relation between boat accelerations and impact level on occupant body regions are compared and verified. Acceleration levels and dummy kinematics was investigated with updates in seat foam design and materials. This study has been conducted in order to avoid injuries for patrol boat occupants and to shed a light on the importance of seat design.
