【摘要】：汽车工业发展至今,制造技术趋于成熟,各式汽车走进千家万户,作为汽车最主要人机交互界面,座椅的舒适度在企业中往往少有关注。当今消费者审美水平日益提高,但汽车座椅设计风格日趋相同,消费者的审美水平难以得到满足。且设计不合理的汽车座椅在长途驾驶之后带来的不是到达目的地的愉悦,而是全身肌肉酸痛和不适。为提升产品品质、提升消费者的驾乘体验,获得更好的市场反馈,需要一种可以提升品质、缩短研发周期、提升舒适度的研究方法。体压分布测试从客观角度展示了座椅设计的合理与缺陷,身体舒适度等级则从主观方面分析人对于舒适度等级的评价。本研究借助这两种方法,去采集座椅最直接展现舒适度的体压分布数据,通过测得的静态数据与身体舒适度等级去获取难以量化的人的感知,并采集分析常见行车路况下驾驶员的体压分布数据,挖掘提升舒适度的方向。采用问卷调查法,对设计定位中模糊之处采用设计师与用户的认知差异分析选出参考意向,采用语义差分法寻找概念座椅的准确定位和设计要素,为后续设计活动提供指导。在设计方案检讨阶段,通过对驾驶员体感数据进行分析,提出方案修正的方向。通过在研发初期就将体压分布数据采集和分析纳入设计流程中,使设计师对座椅舒适度有一定程度的把握,明确舒适度提升的空间,在进行设计活动时,完成抽象的造型定位的同时,明确舒适度的改进方式,提升造型设计的效率,提高造型输出的产品品质。在方案数模完成后采用有限元仿真进一步验证基于体感测量的设计方法的正确性。本文创新地将基于体感测量提升舒适度的方法引入座椅设计开发流程中,为企业缩短研发周期、节约成本、提升品质有极大帮助。
[Abstract]:With the development of automobile industry, manufacturing technology tends to mature. As the main man-machine interface of automobile, the comfort degree of seat is seldom paid attention to in the enterprise. Nowadays, the aesthetic level of consumers is improving day by day, but the design style of automobile seats is becoming the same day by day, so it is difficult to satisfy the aesthetic level of consumers. And the improper design of the car seat after long-distance driving brings not the pleasure of arriving at the destination, but muscle pain and discomfort all over the body. In order to improve the product quality, improve the consumer's driving experience and obtain better market feedback, we need a research method that can improve the quality, shorten the research and development cycle, and enhance the comfort. The body pressure distribution test shows the rationality and defect of seat design from an objective point of view, and the body comfort grade analyzes the evaluation of comfort grade from the subjective aspect. With the help of these two methods, this study collected the body pressure distribution data of the most directly showing comfort degree of the seat, and obtained the perception of the person who was difficult to quantify by the static data and the body comfort level. And collect and analyze the driver's body pressure distribution data under common traffic conditions, mining the direction of lifting comfort. A questionnaire survey was used to select the reference intention from the cognitive difference analysis between the designer and the user, and the semantic difference method was used to find the exact positioning and design elements of the conceptual seat, which provided guidance for the subsequent design activities. In the stage of design scheme review, through the analysis of driver's somatosensory data, the direction of scheme modification is put forward. In the early stage of research and development, the data collection and analysis of body pressure distribution are incorporated into the design process, so that the designer has a certain degree of grasp of the comfort of the seat, and the space for enhancing comfort is clear, and when the design activities are carried out, At the same time, it is necessary to define the way of comfort improvement, to improve the efficiency of modeling design and to improve the product quality of modeling output. The correctness of the design method based on somatosensory measurement is further verified by finite element simulation after the scheme is completed. This paper innovatively introduces the method of lifting comfort based on somatosensory measurement into the design and development process of seat, which can help enterprises shorten the research and development cycle, save the cost and improve the quality.
