| 摘要根据第二次全国残疾人抽样调查初步推算数据，占全国总人口的比例达到了6.34%，由上述数据可以发现，残疾人群体已经成为社会的重要组成部分。残疾人车即轮椅是许多残疾人日常出行需要依仗的重要工具。2013年国内生产的轮椅多达300多万台，虽然无法准确统计国内目前正在使用的残疾人车的数量，但是这个数字应该是巨大的。30048 轮椅的数量如此巨大，但是关于它的配套使用设备却非常少，比如残疾人车在室外行走时，车轮不可避免沾染路面尘土污物，如果残疾人车直接进入房间，难免会将地板弄脏。本课题的开发设计一种残疾人车车轮的清洗装置，装在家门口，使车辆进入房屋前，对轮胎进行自动清洗。 本课题的主要研究内容就是进行残疾人车车轮清洗装置的功能设计、结构设计、强度校核和有限元分析。通过实际的测量和理论计算确定装置的基本参数。在SolidWorks中对车轮清洗装置进行三文建模，装配和有限元分析。运用在机械设计中学到的知识对装置的关键零部件进行受力分析和强度校核。 关键词 残疾人车车轮清洗装置 三文建模 新型机械 强度校核 有限元分析 毕业论文设计说明书外文摘要 Title the development of automatic cleaning device for wheelchair wheels Abstract According to the data initially calculated of the 2nd national disabled persons sampling survey, the proportion of the disabled in the general population reached 6.34%. Thus it can be seen the disabled has become a significant group of society. The wheelchair is an important tool for many disabled people’s traveling. In 2013,over 3 million wheelchairs were produced in home. Despite the lack of an accurate statistic of the quantity of the wheelchairs that are been using, the number is supposed to be enormous. While the number of wheelchairs is extraordinarily huge, the accessory equipment for them is rarely designed and produced. For example, when a wheelchair is used outdoor，the wheels of it will inevitably be stained with the dust and dirt on the road, and then mess up the floor when gets home. This project is to design a cleaning device for the wheelchairs. It can be installed at the door to automatically clean the wheels when a wheelchair enters the room. The main contents of the research of this project consist of the functional design, configuration design, strength check and finite element analysis of the wheel-cleaning device. Basic parameters of the device are obtained by actual measurement and theoretical calculation. 3D modeling，assembling and finite element analysis of the wheel-cleaning device are finished via SolidWorks. Force analysis and strength check of key components of the device are obtained with the knowledge learned in mechanical (machine) design. Key words： wheel-cleaning device 3D modeling new type of machine strength check finite element analysis 目 次 1 绪论 2 1.1 课题的研究背景和意义 2 1.2 残疾人车车轮清洗装置的发展现状和总结评价 3 1.3 课题的主要研究内容 4 2 残疾人车车轮清洗装置的功能设计和原理分析 5 2.1 新型机械的基本设计方法 5 2.2 设计任务 7 2.3 功能设计和原理分析 8 2.4 本章小结 8 3 车轮清洗装置的总体结构设计和基本参数的确定 10 3.1 残疾人车车轮清洗装置外观框架的设计 10 3.2 残疾人车车轮清洗装置传动系统的分析和设计 13 (责任编辑：qin) |
