| Abstract: |
| Objective To design a portable teleoperated rescue device for persons who fell into the sea. Methods The function analysis of rescue device and the design of target properties were performed using the quality function deployment method by summarizing the advantages of existing marine rescuers, marine environment and airborne characteristics. The optimal triangle rescuer was selected from six conceptual design schemes. The simulated analysis of surface pressure distribution was carried out with STAR-CCM+ software. The deformation, stress and strain energy were analyzed with ANSYS Workbench software. The reliability analysis was performed with failure mode and effect analysis (FMEA). Results The triangle rescue device met the requirements of STAR-CCM+ analysis and ANSYS Workbench analysis, and achieved low energy consumption and good agility. The possible causes of failure in reliability analysis were dealt with accordingly. Conclusion The design of portable teleoperated marine rescue device has the characteristics of portability, strong maneuverability and high safety. It can provide great help for maritime rescue and has certain military, social and economic values. |
