【摘要】 人机工程评价分析系统能够在产品设计早期对产品的人机因素进行分析和评价,利用计算机建立人体和产品的计算模型,融入人体生理特征,模拟人操作机器的各种动作,进而将人、机相互作用的动态过程可视化,通过结合人机工程学的各种评价标准和算法,对产品(机)的人机因素进行量化分析和评价。人机工程评价分析技术一方面可以大大降低产品开发的成本,为产品创新提供强有力的支持;另一方面,可以大大降低一些危险性产品的测试风险。本文针对办公家具和办公环境设计的特点,研究了基于人体测量学的三维人体建模技术、运动捕获技术、关键帧提取及插值技术,RULA快速上肢舒适度评估方法、视域分析、静态受力分析等人机评价方法,开发了面向办公家具设计的人机评价分析系统。该系统辅助家具设计师在家具产品建模初期对产品的人机性能进行分析评价,从而帮助设计师改进家具产品模型的设计。该系统是计算机辅助工业设计在家具设计领域中的创新成果。本文主要工作如下:(1)根据办公家具设计的特点,实现了符合中国成年人尺寸标准的人体建模,研究了人体骨骼模型和皮肤模型的绑定算法,满足了用户对人机仿真系统的视觉要求。(2)实现了从运动捕获数据中提取关键帧,并用基于四元数的球面线性插值算法实现了满足办公环境中小幅度的人体姿势的关键帧插值动画。(3)研究了RULA快速上肢舒适度评估法及其计算机实现,视域分析、静态受力分析等人机评价方法。(4)开发了面向办公家具设计的人机评价分析系统,可对人和家具的交互过程进行动态仿真,并给出人机分析结果。更多还原

【Abstract】 Ergonomics Analysis and Evaluation System (EAES) provides the opportunity to analyze and assess the ergonomics factors of a product at early stage of designing. It aims to construct a mathematic model of human body together with the product in computer, combine physiological characteristics, simulate the actions of human operating a machine, thereby visualize the interaction between human and machine, quantize and assess the ergonomics factors of the product based on various ergonomics evaluation standard and method. On one hand, EAES technology could reduce the cost of R&D, give the product strong supports; on the other hand, for hazardous products, it could reduce the risk on testing.As for the characteristics of office furnishing and office environment, this article studied on anthropology based 3D human modeling, motion capturing, key frame extraction and interpolation, RULA fast limb comfort level assessment, visibility analysis, static force bearing analysis etc. An office furnishing design oriented EAES was designed. As a novel application of CAD in the area of furnishing design, it assists designers evaluating ergonomic performance of the product at early stage of modeling, thereby help designers improving their works.The following major achievements were made:1) Constructed models confirmed with Chinese adult stature; studied binding algorithm of skeleton model and skin model, full-filled users’ visual requirement for an ergonomic simulation system.2) Extracted the key frame from captured motion data; simulated the animation of petty actions in office environment using quaternion based sphere linear interpolation algorithm.3) Studied RULA and its implementation in computer, visibility analysis, static force bearing analysis.4) Developed office furnishing design oriented EAES, simulated the interaction between human and furnish, drew the conclusion of analysis.更多还原
