1、上海工程技术大学毕业设计(论文)汽车安全带锁扣的设计提供全套毕业论文,各专业都有摘要安全带锁扣是汽车安全带总成上重要的一环,它的作用是锁住安全带防止挣脱的紧固装置和需解开安全带时的开关作用,其性能的好坏直接影响到汽车安全带的性能,即直接影响到驾乘人员的生命安全。本文对安全带锁扣的结构,工作原理进行了阐述。对国家相关的标准法规进行了仔细研究。依照ECE-R16法规(规定安全带材料及刚性部件的性能要求)、GB14166-2003(机动车成年乘员用安全带和约束系统)等相关法规的标准,使用UGCAD建立了安全带锁扣的三维模型。在确定了各零部件的材料后,对安全带锁扣的锁止过程中的主要部分,如锁舌
2、的运动过程进行受力分析,对主要受力的部件,如锁止片进行了强度校核;同时对锁扣释放过程中的各部件的力传递进行分析和受力计算。通过计算,得出了开启锁扣所需要施加的最小力和按下按钮所需要施加的最小力,并用国家标准中的许用数据进行校核。最后,绘制安全带锁扣各零部件的二维工程图纸和整个锁扣的二维装配图纸。关键词:安全带,安全带锁扣,国家标准,UG,受力分析,强度校核Opinionsandsuggestionsontheparty'smasslineeducationalpracticeAccordingtothecentralandprovincial,municipalunifieddeplo
