【Abstract】 The methods of sonic fatigue test for panel structures near aircraft engine are presented. Techniques for environment simulation, sonic fatigue measurement, determination of loading spectrum, inspection of crack growth in high temperature environment, and for the identification of the fundamental frequency of the panel structure are discussed. Testing results for a typical panel structure of GH140 material are given.更多还原
