【摘要】：人們的很多生產(chǎn)生活活動(dòng)是在坐姿下完成的,因此研究坐姿舒適度有很重要的意義。坐姿舒適度在座椅的設(shè)計(jì)中扮演著越來(lái)越重要的角色,而對(duì)座椅舒適度的研究也逐漸偏重對(duì)坐姿舒適度的評(píng)價(jià)。人性化座椅的設(shè)計(jì)必須滿(mǎn)足舒適度高的要求,以達(dá)到人體舒適坐姿的需求。針對(duì)坐姿舒適度評(píng)價(jià),采用經(jīng)典的光學(xué)動(dòng)作捕捉技術(shù)和問(wèn)卷調(diào)查相結(jié)合的方法對(duì)坐姿舒適度進(jìn)行科學(xué)評(píng)價(jià)。實(shí)驗(yàn)選用美國(guó)Motion Analysis光學(xué)動(dòng)作捕捉系統(tǒng),設(shè)置11個(gè)Eagle數(shù)字捕捉鏡頭,用EVaRT軟件獲取了40名志愿者人體關(guān)鍵點(diǎn)在空間中的點(diǎn)位數(shù)據(jù),采用PCA主成分分析提取特征點(diǎn)的方法提取關(guān)鍵點(diǎn),用MATLAB軟件自主編程對(duì)關(guān)鍵點(diǎn)數(shù)據(jù)進(jìn)行處理和計(jì)算,比較測(cè)試者坐在2種不同座椅上的關(guān)節(jié)角度和力矩?cái)?shù)據(jù)差異。統(tǒng)計(jì)結(jié)果表明,志愿者采用不同的姿勢(shì)坐在不同的座椅上時(shí),軀干、大腿、膝蓋部位的角度和力矩?cái)?shù)據(jù)差異較為明顯。結(jié)合人機(jī)工程理論,利用這些數(shù)據(jù)差異對(duì)坐姿進(jìn)行分析,為座椅設(shè)計(jì)提供理論依據(jù)。這種人機(jī)工程學(xué)理論分析評(píng)價(jià)和問(wèn)卷調(diào)查相結(jié)合的方法,為座椅的舒適度評(píng)價(jià)提供了有效的依據(jù)。
[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.
