Abstract

As the important airborne equipment of casualty aeromedical evacuation, the structure design of aeromedical evacuations stretcher bracket not only has to meet the mounting interface in the civil aviation aircraft and meet the medical rescue requirements during the casualty evacuation, and also has the good bearing capacity of limit load. A structure design of frame-type aeromedical evacuations stretcher bracket is presented in this paper. Based on the finite element method (FEM), the ultimate bearing capacity of the bracket attachment of this structure is analyzed with nonlinear mechanics, and then the intensity and stiffness under the case combinations of limit load are simulated and analyzed to ensure the good security and reliability of the stretcher bracket during the casualty aeromedical evacuation.
