AI Technical Summary

Technical Problem

Existing technologies struggle to identify abnormal changes and early signs of failure that gradually develop in components under thermal shock during high and low temperature impact tests. In particular, before a component reaches significant failure, early anomalies manifest as coupled changes of multiple weak features, making them difficult to identify effectively through single-point results or final state results.

Method used

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.

Benefits of technology

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 anomaly identification in high and low temperature impact tests, and providing a reliable basis for test analysis and problem localization.

Abstract

The application relates to the technical field of reliability test monitoring, and discloses a component thermal mechanical failure early warning system for high-low temperature impact test, which comprises the following modules: a baseline determination module, which is used for acquiring the physical response amount of a measured component at a reference temperature and determining an initial response baseline value; a positive impact analysis module, which is used for determining the residence drift amount, thermal recovery time and thermal mechanical residual offset amount of each stage of a positive path; a reverse impact analysis module, which is used for determining the residence drift amount, thermal recovery time and thermal mechanical residual offset amount of each stage of a reverse path; a criterion construction module, which is used for constructing various early warning criteria; a threshold value determination module, which is used for determining the threshold values of the criteria; an early warning determination module, which is used for determining the criterion triggering result, early warning level and failure cause type; and a result output module, which is used for outputting the result and freezing the threshold value benchmark. The application realizes the identification and early warning of thermal mechanical failure precursors in the high-low temperature impact test process.
