Aircraft Structural Strength Verification Based on Cyber-Physical Fusion

With the continuous development of aviation technology, the complexity of aircraft structures continues to increase, and higher requirements are placed on their strength test verification. Traditional test verification methods can no longer meet the requirements of new aircraft structures for high precision, real-time performance, and data fusion. This paper studies the application of cyber-physical fusion technology in aircraft structural strength testing, focusing on key technologies such as PINN-based virtual model calibration and improvement, and multi-source heterogeneous data fusion. Through these methods, stress field reconstruction, sensor data fusion noise reduction, and dynamic response display under limited measurement point conditions are achieved, thereby significantly improving the accuracy and efficiency of structural strength verification. The research results provide new technical support for structural reliability assessment, early fault diagnosis, and health management, and contribute to proactive maintenance and life cycle management.
