3. 基于寿命的再制造工程再制造工程得以实施的前提是再制造产品的可靠性

3. Remanufacturing project based on life cycle The <br>prerequisite for the remanufacturing project to be implemented is the reliability of remanufactured products. Only by grasping the law of remanufactured products | effect and accurately predicting the impact of different remanufacturing processes on the lifespan can we ensure remanufactured products Ann's lesson. However, due to the diversity of failure modes and degradation mechanisms of remanufactured parts, the complexity of external forces and the uncertainty of boundary conditions, there is also a lack of effective non-destructive testing and simulation analysis methods, and the lack of preparation techniques for high-strength coatings in the Shu environment And the key technology of high energy density rapid prototyping and remanufacturing makes this problem highly challenging and urgent.

3. Life-based remanufacturing engineering<br>The premise of the implementation of remanufacturing engineering is the reliability of the remanufactured product, only grasp the remanufacturing products, the law of effect, accurately predict the impact of different remanufacturing processes on life, in order to ensure the safety of remanufactured products. However, due to the diversity of the failure forms and degradation mechanisms of remanufactured components, the complexity of external forces and the uncertainty of boundary conditions, the lack of effective non-destructive testing and simulation analysis methods, the lack of high-strength coating preparation technology and high energy density rapid forming and re-manufacturing key technologies, so that this problem is highly challenging and urgent.
