Fault analysis of disk strength test for an aero-engine

Analysis and experimental verification of a disk strength test failure for an aero-engine were carried out. Starting from the fault phenomenon, fracture analysis of the test piece and main fixtures was carried out. The basic events that may cause the failure were analyzed and investigated one by one, and the causes of the fault were explored after investigation. Based on this, measures were improved and experimentally verified. The results showed that after taking improvement measures, the disk successfully completed the strength test and experienced stable vibration throughout the entire test process, verifying the effectiveness of the improvement measures. The research improves the design of experimental fixtures and provides reliable experimental data for the development of an aero-engine.
