1、3 吨水车的罐体及水路设计毕业论文专业:汽车工程姓名: 指导教师: 2013 年 6 月 17 日摘要北京建筑大学毕业设计(论文)1洒水车又称为喷洒车、多功能洒水车、园林绿化洒水车、水罐车、运水车。洒水车适合于各种路面冲洗,树木、绿化带、草坪绿化,道路、厂矿企业施工建设,高空建筑冲洗等。其具有洒水、压尘、高、低位喷洒,农药喷洒、护栏冲洗等功能。可以说,洒水车在我们的生活中扮演着越来越重要的角色。这次毕业设计,我详述了洒水车国内外的发展趋势和现状,分析洒水车在设计及使用过程中所遇到的问题,结合指导教师的建议,进行罐体和水路的从新设计,包括确定洒水车车身及罐体尺寸,优化水路设计,改进高压水枪功能,
2、选择合适的二类底盘及加工材料等等,每步设计都按标准进行,以保证满足相关的技术要求。通过理论分析,选用东风金霸洒水车,底盘型号为 EQ1060TJ20D3,发动机选用广西玉柴机器股份有限公司生产的 YCND27-115-30。根据所选择的二类底盘,设计罐体尺寸,水路系统的布局等。并进行罐体尺寸的计算,车身强度的校核等。再根据实际市场情况,选取相匹配的外购件。关键词:洒水车关键词:洒水车 罐体罐体 水路系统水路系统 Abstract北京建筑大学毕业设计(论文)2Water truck is also known as spray vehicles, Multifunction Water truc
