Airocraft Research on Thermal Vibration Test of Typical Rudder Structure
In response to the complex and variable dynamic response of aircraft control surfaces in hot environments,a typical control surface structure is studied.A heating vibration test platform for a typical control surface structure is designed and built for thermal vibration tests on the control surface under different thermal environments in order to obtain the transfer function of the structure under different thermal environments.The research results indicate that the test bench can provide relatively uniform heating on both sides of typical rudder structure,and restore the response characteristics of the structure during real flight by applying external loads through a vibration table.The experimental results indicate that the test method can be used for the combined thermal-vibration tests on aircraft at temperatures ranging from 20℃to 600℃.The test method provides important engineering significance for the study of aircraft thermal-vibrationtests.
