| 英文摘要: |
| For acoustic fatigue failure problems, the acoustic fatigue failure characteristics of thin-walled structures under the high temperature environment were analyzed and studied. Further, it systematically expounded the acoustic fatigue experimental verification technology of thin-walled structures bearing the high temperature. Meanwhile, researches were mainly focused on summaries for the establishment of thermal-acoustic test environment and the infliction of thermal-acoustic loads, the noise test methods in high temperature environment, the test methods of dynamic response and fatigue failure life prediction methods. Given the specific case to illustrate the effectiveness of the experimental verification method in engineering. |
