Influence of Temperature Variation on Structural Dynamics Characteristics of Wing Model

Abstract:

This paper by taking the hypersonic speed wing surface as the research object, according to the basic theory of thermal mode analysis, calculates and analyzes the influence of temperature variation on model vibration characteristics. According to the analysis, the structural natural vibration characteristics can be influenced by different temperature loads obviously. As for the 7075 root fixed wing surface model under the temperature range of 150K~500K, the basic linearity of frequencies of different order modals decreases with the rise of temperature; The structural frequency decreases sharply with the rise of temperature when the temperature is higher than 500K.
