Experimental Study on the Thermal/Vibration Characteristics for a Plate Structure Made of High-temperature-resistant Nickel-based Stainless Steel

摘要：

　　A thermal/vibration test system was established in this paper, using which the key vibration characteristic parameters of a plate structure made of high-temperature-resistant nickel-based stainless steel in a thermal-vibration coupled environment up to 1100℃ (e.g., the modal frequency and modal vibration shape) were experimentally obtained.A self-developed extension configuration of a high-temperature-resistant ceramic pole was used to transfer the vibration signals of the structure to a non-high temperature zone, and the acceleration sensors were applied to identify the vibration signals.The test data were analyzed using a time-frequency joint analysis technique.The research results can provide an important basis for the dynamic performance analysis and safety design of structure under high-temperature thermal-vibration conditions for hypersonic flight vehicles.
