Strategic Study of CAE 2003, Volume 5, Issue 5, Pages 47-54
Computer simulation on heat treatment is the foundation of intelligent heat treatment. The simulation of temperature field, phase transformation, stress/strain in complicate quenching operation has been realized with the three dimensional non-linear finite element method model and the methods of treating for abruptly changed interface conditions. The simulation results basically fit those measured in experiments. A production line with intelligent sealed multipurpose furnace has been developed based on the combination of computer simulation on gaseous carburizing and computer control technology. More than 3 000 batches of workpieces have been processed, and all are up to standard. The application of computer simulation technology can significantly improve the load-carrying ability and reliability of the nitriding and carburizing workpieces, reduce heat treatment distortion, and shorten carburizing duration. It is recommended that the reliable product design without redundancy be performed with the combination between the CAD of mechanical products, the CAE of materials selection and heat treatment, and the dynamic evaluation technology of product reliability.

Marine research equipment is critical for the development of marine science. In recent years, China has made breakthroughs regarding the independent research and development of marine research equipment, and some types of the equipment have reached the advanced international level; however, technologies for the equipment still face various challenges. In this paper, the current status of the marine research equipment is reviewed, including research vessels, underwater vehicles, buoys, marine sensors, and marine observation networks. The problems encountered in the technical development of China’s marine research equipment are analyzed from the aspects of key components, technology research and development, data management, basic support, and demand matching. The future development trends are summarized, namely, green, unmanned, intelligent, and collaborative development for deep sea and polar sea research needs. Meanwhile, the key and core technologies for the overall and each category of marine research equipment are analyzed. To provide references for further promoting the rapid development of marine research equipment, the following development suggestions are proposed: sorting out the technical shortcomings, strengthening the coordination of resources to improve supporting capacity, improving the innovation mechanism to promote interdisciplinarity, strengthening the role of the market to promote the industrialization process, and relying on advanced scientific research platforms to expand international cooperation.
