Research

The CAE Pressure Intelligent Manufacturing team aims to meet the demands in the fields of petrochemicals, energy, aerospace, nuclear safety, GF, et al. They focus on developing core equipment based on advanced finite element technology.

In the field of design and analysis of pressure equipment and pipeline, the team focuses on conducting detailed analysis, calculations, and experimental validations for various failure modes that occur in different service environments. They employ innovative design methods to ensure the intrinsic safety of equipment and pipelines. The main research work includes the development and design of new structures, structural optimization, safety assessment of in-service equipment, and the development of specialized software.

       In the field of metal additive manufacturing and laser manufacturing science and engineering, supported by national key research programs, key projects of the National Natural Science Foundation, and specific projects of the key research and development program in Sichuan Province, research has been conducted on stress-strain, cracking behavior, and mechanical properties of additive components in the laser additive manufacturing process. Additionally, work has been done on complex digital modeling for metal biomimetic additive manufacturing, high-performance aluminum alloy and titanium alloy laser welding processes, and performance evaluation in service. Furthermore, research on laser cleaning and laser shock peening has also been conducted.
