Abstract:
Objective To This study aims to analyze the airworthiness compliance of transport stretchers for severely injured patients to ensure their safety and effectiveness in aeromedical rescue.Methods Through finite element modeling and analysis,using the analysis/calculation verification method(code MC2)in the Means of Compliance(MC),the structural static strength,stiffness,load and internal force of the transport stretcher were evaluated,and the damage tolerance assessment and vibration analysis of the connecting structure were carried out.Results The analysis results showed that the safety margins of the main structure and various components of the transport stretcher were all greater than zero,meeting the airworthiness design requirements.The damage tolerance analysis of the connecting structure showed that after the stretcher was installed,the aircraft body structure met the design requirements and did not change the inspection threshold value and interval.In addition,the performance analysis results of the transport stretcher in standard and enhanced vibration environments both indicated that the probability of failure was extremely low.Conclusion The transport stretcher meets the DO-160G standard in design and function and meets the requirements of relevant aviation regulations,providing scientific basis and practical guidance for the efficiency and safety of the aeromedical rescue system.
