Abstract

In order to study the random vibration fatigue failure mechanism of turbo-rotor blades under the excitation of high-temperature airflow, as a basic research on this question, thin-walled plates were adopted as simulation and experimental objects.By high-temperature test chamber and shaking table tests, the axial dynamic stress responses of test pieces were obtained under different temperature and vibration level.Based on the theory of Miner linear fatigue accumulative damage, an improved rain flow counting method was used to estimate the fatigue life of thin-walled structures.Using an integrated test bench composed of a high-temperature test bench and a shaking table , the stress and life data of the test pieces under actual working conditions were obtained, and the simulation and experimental results were compared.The results show that by simulation the failure position of the test pieces can be detected accurately, the stress response error is less than 5.6%, the maximum error of the frequency responses is about 1%and the fatigue life is less than 28.6%, which proves that the analysis method for the random vibration fatigue estimation in high temperature condition is effective and accurate.
