1、摘要敞篷车车顶的结构设计与控制系统设计摘要敞篷车是指带有可开启车顶的汽车,不但拥有普通汽车的用途,而且可使人们享受阳光,与大自然亲密接触。随着我国经济快速发展和汽车市场的日益成熟,敞篷车日益受到消费者的青睐,销售量不断攀升。而中国市场完全由国外汽车厂商垄断,民族品牌急待发展成长。论文首先对国内外车顶目前研究现状进行分析,给出几款成熟的车顶产品,如宝马、奔驰等,分析软顶与硬顶的技术差异,着重介绍硬顶技术的优异性,结合需求分析给出本论文的整体设计。其次,针对关键技术,给出硬顶敞篷车的机构设计方案,结合车身参数信息,模仿专利US6322130八连杆机构,利用机械设计连杆计算方法,确定结构件参数。使用
2、CATIAV5对整个结构图进行绘制,利用其DMU仿真模块对整机进行运动仿真。利用材料力学方法对关键零部件进行力学校核,使用ANSYS对关键结构件进行有限元分析,判断零件的刚度与强度,根据车顶运行过程中的受力情况,对关键元器件进行选型计算,结合各个供应商给出的元器件参数,确定元器件的具体型号以及参数,并校核。最后利用Profibus-DP现场总线技术对整个车顶升降装置进行控制设计,给出控制系统总体布局以及控制原理图,并对控制系统软件层面进行了设计。鉴于国内敞篷车设计领域的空白,本课题以某型轿车车身为平台,对敞篷车车顶技术深入研究,旨在抛砖引玉,引领敞篷车相关领域研究,为车顶前期机构设计和可靠性研
