一种用于高低温冲击试验的构件热机械失效预警系统
By using a component thermomechanical failure early warning system, the response changes during high and low temperature impact tests are continuously analyzed. Criteria are constructed and combined with threshold judgment, which solves the problem of difficulty in identifying progressive anomalies in components in the existing technology, and realizes early warning and reliable failure identification.

AI Technical Summary
Existing technologies make it difficult to identify gradual abnormal changes and failure precursors of components during high and low temperature impact tests in a timely manner. In particular, before the components reach significant failure, early anomalies manifest as coupled changes of multiple weak features, which are difficult to identify effectively through single-point results or final state results.
A component thermomechanical failure early warning system is provided, including a baseline determination module, a forward and reverse impact analysis module, a criterion construction module, a threshold determination module, and an early warning judgment module. By continuously analyzing the response changes of the tested component under different thermal shock paths, the system constructs criteria such as path asymmetry, total dwell drift, recovery hysteresis asymmetry, and irreversible cumulative cycle increment, and establishes thresholds in conjunction with healthy cycles to determine the early warning level and failure attribution type.
It can reflect the abnormal changes and failure precursors that gradually form in components under thermal shock at an earlier time, improving the timeliness, stability and comparability of abnormal identification in high and low temperature impact tests, and providing a reliable basis for test analysis.
