RESUMEN
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.
RESUMEN
Objective To develop rescue device for pilots in air accidents and solve the problem that it's difficult for medical staff to carry out on-board rescue because of the height from the ground to the cockpit edge of the fighter plane. This device with hydraulic system is multi-use: it can be joined to the plane as a ladder and tied in an ambulance as a stretcher. The medical support level of air force dump and station will be improved after using it. Methods 6082 aluminium alloy for aeronautic with advanced and matured technology was utilized to weld the principal part. The fissions can be fitted together and drawn out. The cantilever with hanger was applied. The active and diagonal crutches and the separable composite structure were also used. Results With this device, two staff can board the fighter plane to carry the wounded pilot to the sliding seat which is stably controlled by hydraulic system and then after quick sliding and separating from the device, the seat become a stretcher, and thus it can avoid the second carrying to the pilot. Using this device, the rescue work on-board become faster, more steady and safer. Conclusions This device can provide on-board rescue for pilots of forced landing in air accidents and it can be configured in a new kind of outfield ambulance for both military and civilian purposes. Because of being simple in frame and light in weight, it is easy to take or transport.
