Popis: A self-developed extension configuration of high-temperature ceramic pole was used to transfer the vibration signals to non-high temperature zone, and the vibration signals of composite wing structure under high-temperature environment were identified by the ordinary acceleration sensors. The experimental measurement on the key vibration characteristic parameters of composite wing structure under high temperature thermal vibration environment up to 1100°C (e.g., the natural frequency, mode shape) was realized. The experimental results can provide an important basis for the dynamic performance analysis and safety design of composite wing structure under high-temperature thermal vibration conditions.
