零件与结构的失效与安全服役科学研究机械零件与结构的失效规律、发展相医的

Failure and safety of parts and structures Scientific research on the failure laws of mechanical parts and structures, the development of safety evaluation theories and safety assurance technologies for medical professionals. The failure of parts and structures depends on the type of mechanical product and the service scenario. It can include deformation failure (elastic and plastic deformation), fracture failure (initial fracture, new cracking, fatigue fracture, environmental fracture), and clothing damage There are many types of failure (wear, corrosion, epidemic). At the theoretical level, the safe service of parts and structures includes structural strength design theory, fracture force, damage mechanics, fatigue theory, corrosion theory, friction theory, reliability theory and structural integrity theory; at the technical level Including safety testing and inspection, safety monitoring and control, maintenance and remanufacturing technology, etc. Although the research on the failure and safe service of mechanical parts and structures does not focus on the innovation and expansion of high-function mechanical production, but the realization of almost all high-tech mechanical products must be premised on their safe operation. Safe service has also become an important "mbling technology" in modern mechanical engineering.

The failure of parts and structures and the failure of mechanical parts and structures of scientific research in safety service, the safety evaluation theory and safety technology of developing phase medicine. The failure of parts and structures may include deformation failure (elasticity and plastic deformation), fracture failure (initial fracture, brittle new crack, fatigue fracture, environmental fracture), and clothing damage failure (wear, corrosion, epidemic labor) according to the different types of mechanical products and the choice of service conditions. The safety service of parts and structures includes the theoretical basis of structural strength design theory, fracture force, ajury mechanics, fatigue theory, corrosion theory, grinding theory, reliability theory and structural endothel theory, and includes safety testing and testing, safety monitoring and control, maintenance and remanufacturing technology at the technical level. Although the study of mechanical parts and structure failure and safety service itself does not focus on the innovation and expansion of high-function mechanical production, the realization of almost all high-tech mechanical products must be based on its safe operation, therefore, the safe service of parts and structures has become an important modern mechanical engineering "enabling technology".

The failure and safe service of parts and structures scientific research on the failure law of mechanical parts and structures, development of medical safety evaluation theory and safety assurance technology. According to the different types of mechanical products and service conditions, the failure of parts and structures can include deformation failure (elastic and plastic deformation), fracture failure (initial fracture, brittle new fracture, fatigue fracture, environmental fracture), and surface damage failure (wear, corrosion, epidemic). On the theoretical level, the safe service of parts and structures includes the theoretical basis of structural strength design theory, fracture force, scratch mechanics, fatigue theory, corrosion theory, abrasion theory, reliability theory and structural integrity theory; on the technical level, it includes safety test and detection, safety monitoring and control, maintenance and Remanufacturing technology, etc. Although the research on the failure and safe service of mechanical parts and structures does not focus on the innovation and expansion of high-tech mechanical products, almost all the realization of high-tech mechanical products must be based on their safe operation.
