For the problem of dynamic response and fatigue failure of titanium alloy acoustic liner under high temperature vibration environment, the vibration characteristics of titanium alloy acoustic liner under high temperature environment were studied by combing simulation analysis and test. The results showed that the calculation results of first-order natural frequency of titanium alloy acoustic liner at 200 ℃ were in good agreement with the test values, and the error was within 8%. Under 40
