5.1.2 研究范围根据机被产品服役过程的特点,零件与结构的失效与安全

5.1.2 Research scope <br>According to the characteristics of the service process of the machined products, the research on the failure and safe service of parts and structures should include the contents of failure evaluation and life prediction, repair and remanufacturing, safety testing and online health monitoring. <br>1. Failure Evaluation and Life Prediction <br>major study to explore the failure of the law and structure of parts evaluation and life prediction of failure, the failure to reveal information purposes too, as well as the critical value parts and structural damage, and to forecast the life of the related products. It involves aspects such as intersection and damage, fatigue and fracture, corrosion and wear, life prediction and safety assessment. While uncovering the failure rules of the structure and accurately predicting the life, applying the newly discovered knowledge is expected to improve the safety design of mechanical products and contribute to a new safety design theory.
