Abstract
Objective To develop an airborne multi-person stretcher support system meeting aviation ultimate load requirements and being compatible with the PLA's current general-purpose medical stretchers,so as to solve the problems of a certain transport aircraft in strength and adaptability.Methods The airborne multi-person stretcher support system was composed of pole components,suspension strap components and locking mechanisms.The pole components included two horizontal crossbars,two sidewall vertical bars,two central vertical bars and two diagonal braces,which were made of 30CrMnSiA aerospace-grade special steel;the suspension strap components consisted of lifting straps,stretcher suspension straps,buckles and hooks,which were woven from multi-layer polyester material;the locking mechanisms comprised locking brackets and folding brackets.Theoretical calculations were performed using finite element analysis to identify critical cross-sections of the pole components and optimize their dimensions;a dedicated static strength testing platform was constructed to conduct component-level and system-level static strength validation tests for the stretcher support system.Results Finite element analysis indicated that the pole components could be designed as square channel steel with an external cross-sectional outline of 50 mm×40 mm(length×width)and a thickness of 2 mm,and the critical cross-sections included the outer regions of the horizontal crossbars and the central regions of the central vertical bars;static strength test showed no structure failures occurred in the pole components,folding brackets and locking brackets when they were subjected to forward(+x)9.0G,lateral(-y)3.5G and downward(-z)4.5G loads,suggesting the components met the static strength requirements.Conclusion The airborne multi-person stretcher support system can be installed on the aircraft platform,which gains advantages in simple structure,easy assembly and disassembly,light weight,high strength and high compatibility with the PLA's current general-purpose medical stretchers.[Chinese Medical Equipment Journal,2026,47(1):28-34].关键词
