中文摘要: |
为给电动自行车儿童座椅标准提供有效的参考数据,利用CAE系统建立了电动自行车货架、一款有束缚装置座
椅的三维模型。结合电动自行车相关标准和我国儿童体重、身高分布状况,利用CAE系统中的力学分析模块,在电动自
行车匀速行驶、紧急制动、弯道行驶等工况下分别对有、无束缚装置的座椅进行了力学分析,研究了座椅的安全系数、应
力分布规律、最大应力发生位置及最大变形发生位置。同时利用CAE系统研究了座椅踏板的强度及变形分布规律,研
究了足部防护装置的大小对保护效果的影响。 |
英文摘要: |
To provide effective reference data for a standard of electric bicycle child seat. an electric bicycle rack and a
seat with restraint device was built in CAE system. Under combining electric bicycle standards and the distribution of
Chinese children's weight and height, a seat with and without restraint device was mechanical analysis when electric
bicycle was traveling at constant speed, emergency brake. and turn driving in a CAE system. Seat safety factor, stress
distribution. maximum stress location and position of maximum deformation were researched. Strength and deformation
distribution for seat pedal was studied. The effect of the size of protection device was considered. |
