EducationWork ExperienceSocial PositionSocial ActivitiesResearch1.Pressure Vessel Design and Performance Enhancement This direction takes pressure vessels and process equipment as objects, applies advanced analysis and design theories and numerical simulation technologies to carry out equipment strength analysis, safety evaluation, performance enhancement and optimization design, and solves technical problems that cannot be solved by conventional design methods. 2. New Energy Equipment Technology This direction applies the traditional process equipment and its design method to new energy fields such as light energy, hydrogen energy and nuclear energy. For example, the large molten salt storage tank is a key equipment in the photovoltaic power generation plant, and we have carried out the structural strength analysis of this equipment to solve the technical problems in its construction and operation. In view of the technical problems in its construction and operation, we have carried out structural strength analysis, thermal deformation and thermal stress analysis, creep fatigue analysis, and flow field and heat transfer analysis of the preheating and salt feeding transient processes of this equipment. 3. Fatigue and fracture This direction applies fundamental theory of fracture mechanicsis to analyze the fracture problem of engineering structure, and theoretically put forward crack transition expansion, crack group equivalence and other fracture mechanics models.
