【摘要】 造型设计是人类创造力的外在表现,它凝聚了人类的智慧和价值观念,是时代信息反馈的总和,是经济基础、社会意识、文化艺术的高度凸现。从一百多年前发明了汽车至今天,汽车既作为社会商品又作为人类行走器官的沿伸工具。同时它也是艺术产品,优美的造型不仅给人带来美的视觉感受,其时代感流行性、速度感、安全感,都是通过造型艺术来满足与使用人身分相适应的心理诉求。汽车造型具有明显的科学技术和文化艺术的双重特征,反映了当代科学发展的动向。纵观汽车的发展历程,在不同的历史发展阶段,汽车总是通过造型艺术来体现其时代流行美感。汽车造型艺术的重点是外型设计,而外型设计的主体是车身设计。四十年代以前的设计是由工程师负责,他们长于运用机械式逻辑思维设计,而不善于运用艺术形象思维。二战后,全球汽车工业发展突飞猛进,造型艺术已成为汽车设计的一个重要和前卫领域,在这一领域之中,不乏有艺术家、生理学家、心理学家、材料学家等参与,使艺术创造、人体工程学、空气动力学与汽车造型完美的结合,设计出理想的车身外型。造型设计是人在情感上对均衡、节奏、韵律、和谐、对比等形式的审美需要,是人对自己一种历史的文化心理认识和沉淀,人的价值观念的体现。而人类认识事物都是从感知开始的。视觉又是人类认知世界的重要的途径,近年来随着生物医学技术的不断发展,人们对脑电信号(EEG)的研究也逐步加深,基于感知的脑电信号的研究逐渐成为近年来研究的焦点课题之一,研究学者通过大量实验证明,事件相关电位可以敏感地反映出情绪变化在脑内的活动过程,为人脑高级功能的研究提供了一种客观可行的方法。通过查阅相关文献和进行相关实验,本论文研究方向大致向以下两方面展开：一是采用现代信号分析处理方法的基本原理,研究并实现脑电信号特性分析和特征提取的更加有效和快速的算法；二是研究基于认知脑电的造型评价。通过对脑电信号的采集、提取、处理,统计比较,最终发现认知加工任务中,不同造型诱发下脑电活动的具有明显的差异性,而且被试者对于汽车造型的选择在脑电图中也有明确体现,基于脑电认知的汽车外观造型评价方法的提出,可以运用于企业的实际造型设计工作中,对汽车外观的分析、评价及设计工作流程将产生较好的现实指导意义。这种方法可以使整个工作流程更加科学完善、深入有效。更多还原

【Abstract】 Modeling design is external manifestations of human creativity, and it represents humanity’s wisdom, values and sum of economic base feedbacks, and also is the height of emergence of the economic basis, social consciousness, arts and culture. From more than100years ago to automobile inventing today, the automobile is as both social commodity and human extended walking organs. Besides, it is also artistic product, the exquisite modeling not only brings their sense of beauty of visual feeling to the human, also its modernity epidemic, speed feeling, sense of security, all satisfy and adapt to the identity of the psychological demands by using of the plastic arts. The automobile modeling with combined characteristics of obvious science, technology and the cultural arts has reflected the trend of the development of contemporary scientific trend. In different historical stages of development, the automobile always manifests its popular sense of beauty through the plastic arts of its time.Automobile styling is the focus of automobile intervetebral design; whitch is the main body design. Before40s, the design of Automobile is responsible by engineer. They excelled in the utilization mechanical type with logical thinking, but did not well in utilizing the artistic thinking in images. After World War Ⅱ, with the rapid development of the global automobile industry, the plastic arts have become an important car design and avant-garde areas. In this area, no shortage of artists, physiologists, psychologists, materials scientists, etc. so that participation in artistic creation, ergonomics, trains’aerodynamic and automobile styling makes the design of the combination of ideal body shape perfect.The modeling design is human emotionally needs in balance, form, rhythm, harmony, contrast; is a kind of history cultural psychology understanding and the precipitation, human’s values reads manifests to itself. But we knew thing beginning from the perception. Human visual perception is also an important cognition approach. In recent years, along with bio-medicine technology sustainable development, people research the Electroencephalogram (EEG) also gradually deepens. It has gradually become one of focal topics in recent years based on the sensation EEG’s research studied. Through a large number of experiments researchers on the EEG proved that the event-related potentials can be sensitive to emotional changes and reflect activity in the brain. It also has provided one objective feasible method for the human brain high-level function’s research.After the experiments involved with consulting relative article, there are approximately two contents in this thesis based on the foundation:first, the basis theory and methods using classic and moden singal proeessing analysis are studied, especially the effective and fast algorithm about the exrtraction and analysis of EEG features; second, automobile modeling evaluation research based on cognition EEG will be engaged in. Through acquisiting, extracting, processing the EEG signal, we finally discovered in the cognition processing task that the EEG activity are of obvious difference under various modeling evoked, moreover the testees’automobile modeling choices in the electroencephalogram manifests explicitly. The presentation of this approach, Automobile Modeling Evaluation Based on Cognition EEG, can be applied to the actual modeling design, and will have a better practical guiding significance to the appearance of the vehicle analysis, evaluation and design of work processes analysis. This method would help the workflow to be more scientific consummates thoroughly and effectively.更多还原
