The Design Of Rescue Simulation Training Cabin And Study On Its Dynamical Characteristics

The rescue training simulator designed in this paper usually been adopted to train the life-guard in harsh conditions in the laboratory. Relative to the actual training, it has the merits of efficiency and cheap, and will become one of main methods of rescue training. At present, actual training is the main way of rescue training in our country. There is no actual training in the rough sea conditions to ensure security. The Dalian Maritime University based on the feature of helicopter rescue and wants to build a helicopter rescue simulation training system which includes:translational system, six-freedom degrees platform, cabin-winch system and rescue environment simulation system. The system could replace most mission of helicopter hovered rescue in rough conditions.In this paper, it focuses on analyzing and research the structural design and kinetics of helicopter rescue training simulation cabin. Follow the general requirements and design the structure of the cabin and checking in finite element software. Study the dynamic analysis of the cabin by way of simulating the real rescue action to find out the maximum condition and analyzed, in order to ensure the security when the cabin is moving.Firstly, the pose data of the rescue helicopter in training was collected, and get the displacement of simulation cabin by inverse solution the data. According to syllabus of the life-guard and the facts, we drafted the crafts and technical requirements of the structure of the simulation cabin, and defined the general requirements and parameters of the cabin.Secondly, the cabin was designed in accordance with requirements. According the general requirements and the fact the skeleton of the cabin and plate were designed, skin, beam, the arm of winch. Analyzed the designed parts based on maximum load conditions, and identified the stability and material of the structure.Finally, the dynamic and the finite element of the cabin in maximum conditions were studied. We build the model of the dynamic and the finite element. Get the force of the cabin in time by put in the training pose data of rescue helicopter. And the cabin when get the most force and acceleration was simulated by finite-element analysis.The analysis shows that the simplified model is same as the real structure of the cabin, the simulation is an accurate reflection of the mechanical properties of the rescue simulation training cabin. The conclusion confirmed that the strength and safety of the rescue simulation training cabin were satisfactory in static and dynamic rescue training.
