1、 1 中英文翻译 外文原文： Application and Development of Simulation Technology in Manufacturing Abstract Simulation is a necessary aid for product development and manufacture. It can greatly reduce losses, save costs, shorten product development cycles and improve product quality. Since 1970s, Advanced Manufac
2、turing Technology (AMT) has been studied and applied by institutes and enterprises all over the world as a strategy to adapt to global competition of manufacture. Application and development of AMT promotes the research and application of simulation technology in manufacturing. From the viewpoint of
3、 evolution, the application fields of simulation technology in manufacturing are obviously enlarged. Addition to conventional fields of manufacture (including production planning, machining, assembling and testing), simulation tools are developed in the fields of product design and development, supp

Interactive, due to technology of graphics and sensory-motor； 3. Integrated, such as VM, VPD, VFT, etc. According to different objects to be simulated, simul
5、ation in manufacturing can be classified as: 1. Product-oriented 2. Production-management-oriented； 3. Process-and-device-oriented； 4. Other. This paper will describe simulation in manufacturing from above aspects. And Virtual Reality (VR) and Virtual Manufacturing (VM) are introduced in the last se
