基于坐姿分析的座椅舒适度测试与评价
发布时间：2018-09-12 17:34
【摘要】：人们的很多生产生活活动是在坐姿下完成的,因此研究坐姿舒适度有很重要的意义。坐姿舒适度在座椅的设计中扮演着越来越重要的角色,而对座椅舒适度的研究也逐渐偏重对坐姿舒适度的评价。人性化座椅的设计必须满足舒适度高的要求,以达到人体舒适坐姿的需求。针对坐姿舒适度评价,采用经典的光学动作捕捉技术和问卷调查相结合的方法对坐姿舒适度进行科学评价。实验选用美国Motion Analysis光学动作捕捉系统,设置11个Eagle数字捕捉镜头,用EVaRT软件获取了40名志愿者人体关键点在空间中的点位数据,采用PCA主成分分析提取特征点的方法提取关键点,用MATLAB软件自主编程对关键点数据进行处理和计算,比较测试者坐在2种不同座椅上的关节角度和力矩数据差异。统计结果表明,志愿者采用不同的姿势坐在不同的座椅上时,躯干、大腿、膝盖部位的角度和力矩数据差异较为明显。结合人机工程理论,利用这些数据差异对坐姿进行分析,为座椅设计提供理论依据。这种人机工程学理论分析评价和问卷调查相结合的方法,为座椅的舒适度评价提供了有效的依据。
[Abstract]:A lot of people's production and life activities are completed in sitting posture, so it is very important to study the comfort of sitting posture. Sitting comfort plays a more and more important role in seat design, and the research on seat comfort has gradually focused on the evaluation of seat comfort. The design of humanized seat must meet the requirement of high comfort, in order to meet the need of human body comfortable sitting posture. Based on the evaluation of sitting comfort, the classical optical motion capture technique and questionnaire survey were used to evaluate the sitting comfort scientifically. In the experiment, the Motion Analysis optical motion capture system was used in the experiment, and 11 Eagle digital capture lenses were set up. The data of the key points in the human body of 40 volunteers in space were obtained by EVaRT software. The key points were extracted by PCA principal component analysis (PCA), and the data of key points were processed and calculated by MATLAB software. The differences of joint angle and torque data between two different seats were compared. The statistical results show that when the volunteers sit on different seats in different positions, the data of torso, thigh and knee position are significantly different. Combined with ergonomics theory, these data differences are used to analyze the sitting posture, which provides theoretical basis for seat design. The method of ergonomics theory analysis and questionnaire survey provides an effective basis for seat comfort evaluation.
