A REVIEW OF THE HISTORY OF CHINA'S MACHINE DESIGN METHODS AND THE PROSPECT

This paper examines the history of China’s machine design methods and its status quo. First of all, it discusses machine design methods in ancient China. (1)The design idea of creation by the intelligent and exposition by the ingenious. (2)The design principle of the dependence of workmanship on criteria. (3)A macroscopic view of the object of design. (4)The design method of manufacture emphasizing shape. (5)Technological requirements on excellent material and consummate skill. Second, it discusses machine design ideas in ancient China. (1)The system idea in machine design, (2)The idea of machine design.(3)The idea of standardization in machine design. (4)The idea of automation in machine design. Finally, it discusses the status quo and a look ahead of the theory of machine design in China.

Identifying subassemblies and understanding their functions during a design review in immersive and non-immersive virtual environments

Design review(DR)is a product development(PD)activity used to inspect the technical characteristics of a design solution.Immersive virtual reality(IVR)technology enables the presentation of spatial information and interaction with 3D CAD models inside an immersive virtual environment(IVE).Such capabilities have shown the potential to mitigate the cognitive load needed for the visual perception of spatial information and,consequently,enhance design understanding and DR performance.Thus,an increasing number of studies have explored the effect of IVR technology on DR activities in different domains.However,determining when the implementation of IVR technology rather than a conventional user interface for DRs in mechanical engineering PD projects will be beneficial remains unclear.Hence,a conceptual DR experimental study was conducted to investigate the differences in the ability of engineering students to identify mechanisms and understand their functions when a design solution for a technical system is presented in an IVE by IVR technology and in a non-immersive virtual environment(nIVE)by a conventional user interface(monitor display,keyboard,and mouse).Data were collected by performing DR tasks and having participants complete a prior experience questionnaire,presence questionnaire,and mental rotations test.Findings of the study indicate that IVR does not support an enhanced ability of engineering students to identify mechanisms and understand their functions compared with a conventional user interface.
