基于人机工程学自行车的设计 (修复的)

基于人机工程学自行车的设计基于人机工程学自行车的设计I摘要随着人们环保意识和健身意识的增强，以及自行车本身的诸多优点，自行车越来越受到人们的青睐。然而当人们骑行不适合自己身体结构的自行车，随着时间的持续就会产生疲劳和不适，严重的还会影响到人们的身体健康。基于人机工程学的自行车设计是自行车设计的一个重要研究热点。自行车与人体有多个部位紧密接触，在设计时应统筹考虑自行车的结构和骑自行车的人的生理特点，才能做到人与自行车的协调统一。在自行车设计中考虑人的因素，对其进行人机工程学设计是自行车发展的必经之路。正是基于此，本文首先分析自行车的结构和人体特性，并找出他们之间的联系点，然后应用人机工程学的相关理论进行自行车设计。关键词：人机工程学；自行车系统；自行车性能；自行车设计结构；自行车的机械因素；自行车动态特性基于人机工程学自行车的设计IIAbstractAlongwiththepeopleenvironmentalprotectionconsciousnessandconsciousnessoffitnessenhancement,aswellasthebikeitselfhasmanyadvantages,thebikemoreandmorepeopleofallages.Howeverwhenpeoplerideisnotsuitablefortheirownphysicalstructureofbicycle,astimecontinuedwillproducefatigueanddiscomfort,seriouswillinfluencepeople'shealth.Basedontheergonomicsdesignofbicyclebikedesignisoneofthemostimportantandhotresearchtopics.Bicycleandthehumanbodyhasmanypartsofclosecontact,inthedesignshouldconsiderthestructureofbicycleandbicycleridingpeople'sphysiologicalandpsychologicalcharacteristics,canaccomplishpersonandbicycleisharmoniousandunified.Seniorhighschoolentranceexaminationinbicycledesignconsiderthehumanfactor,carriesontheman-machineengineeringdesignisthedevelopmentoftherouteonemusttakethebike.Itisbasedonthis,thisarticlefirstanalysisofbicyclestructureandpropertyofthehumanbody,andtofindouttheconnectionbetweenthem,andthentheapplicationofergonomicstheorybicycledesign.KeyWord:Ergonomics;bicycledesignsystem;bicycleperformance;bicyclestructure;mechanicalfactorsofbicyclebike;dynamiccharacteristics基于人机工程学自行车的设计III目录摘要...................................................................................................I第一章人一自行车系统的关系分析.................................................11.1设计原则......................................................................................11.2形态设计......................................................................................11.3人与支撑部件关系......................................................................11.4人与动力接受部件关系..............................................................21.5人与传动部件关系......................................................................21.6人与工作部件关系......................................................................2第二章影响自行车性能的人体因素.................................................42.1人的体格因素..............................................................................42.2人的下肢肌力..............................................................................42.3人的输出功率..............................................................................42.4人的脚踏速度..............................................................................42.5人的平衡机能..............................................................................42.6人的手和握力..............................................................................52.7人的疲劳......................................................................................53.1齿速比...........................................................................................63.2曲柄...............................................................................................63.3三接点位置正确的骑车姿势......................................................6第四章影响自行车的机械因素.........................................................84.1车把的分析与改进......................................................................84.1.1车把的高度...............................................................................................84.1.2车把的宽度...............................................................................................84.1.3车把的位置...............................................................................................84.1.4把手的形状...............................................................................................94.1.5把手的弯度...............................................................................................94.2车闸.............................................................................................104.3车架结构尺寸确定....................................................................114.3.1车架规格.................................................................................................124.3.2轮距…....................................................................................................13基于人机工程学自行车的设计IV4.3.3后心距....................................................................................................134.4车座的改进与分析....................................................................134.4.1车座存在的问题.....................................................................................134.4.2优化的方面和措施.................................................................................144.5靠背的分析与设计....................................................................164.5.1靠背的高度.............................................................................................164.5.2靠背的宽度.............................................................................................174.5.3靠背的角度.............................................................................................174.5.4靠背的
