英文摘要： Based on the background of aircraft assembly process, this project delves into the wide range research which includes the behavior of human's habit, the typical posture of manufacturing, the feeling and its cognitive mechanism about people's attitude towards the working environment. This study is under the guidance of an interdisciplinary theory of cognitive science, ergonomics, information science and technology and knowledge. According to mechanism of human nature, a method to predict human global approximate posture is developed according to the given posture generation condition；an optimized obstacle-avoiding algorithm to calculate local posture accurately is proposed by using the artificial potential method；the method to calculate whole virtual human posture is constructed based on both global posture approximate generation and local posture accurate calculation；Advanced Smart Object ASO() is defined,and ASOprovides the intelligent model and core techniques for the ergonomics simulation and its automatic generation；Propose a method of human-machine task planning and corresponding automatic generation of simulation,and it is applied to avoid massive direct interactions during the creation of ergonomics simulation, and make the simulation reusable; establish a quantificational calculation and assessment of virtual human work efficiency based onArtificial Neural Network; a prototype of Ergonomics Simulation Automatically Generate System (ESAGS) is developed to validate the feasibility and correctness of all the theories, techniques and algorithms of ergonomics simulation automatic generation proposed in this dissertation.In general, this project can not only solve some problems in the software currently used in the aircraft digital manufacturing, but also is a multi-disciplinary , cross-cutting and innovative research, with a strong practical use and forward-looking.
