Research on strength testing technology for aircraft cargo hold restraint nets

In response to the limitations of traditional transport aircraft cargo hold barrier net test methods in terms of boundary support and load simulation, an innovative test technology framework was proposed. By establishing the full net surface cargo simulation technology supported by rigid boundary, the support constraints distributed at multiple points in actual working conditions are effectively reproduced. Furthermore, based on multi-sensor synchronous monitoring, a precise testing method for flexible structures was developed. This method tracks real-time interface load data at connection points, quantitatively analyzes the load distribution along load transfer paths, and systematically evaluates the mechanical response characteristics of the restraint net. The results demonstrate that this approach ensures the reliability of test data while significantly improving the stability of strength verification for flexible structures, successfully addressing the issues of uneven loading and result fluctuations caused by structural flexibility in traditional tests. The proposed test technology framework provides a reusable solution for strength verification of similar flexible structures, offering valuable engineering references for the safe design of air cargo system.
