美国DOT汽车安全技术法规资料(FMVSS)

DOT认证制度美国汽车安全技术法规FMVSS美国是世界上法律法规体系最完备的国家之一，政府从维护整个社会和公众的利益出发，将汽车产品的设计与制造纳入社会管理的法律体系中，对汽车产品的设计和制造专门立法，授权汽车安全、环保、防盗和节能的主管部门制定汽车技术法规，并按照汽车技术法规对汽车产品实施法制化的管理制度，实现政府对汽车产品在安全、环保、防盗和节能方面的有效控制。

美国联邦政府根据国会通过的有关法律，如《国家交通及机动车安全法》《机动运载车法》《机动车情报和成本节约法》《噪声控制法》《大气污染防治法》及《机动车辆防盗法实施令》等为依据，分别授权美国运输部（Dot）和美国环境保护署（EPA）制定并实施有关汽车安全、环保、防盗和节能方面的汽车法规，以达到政府对汽车产品安全、环保、防盗和节能这几方面有效的控制。

本文现专门就美国汽车安全技术法规的制修订和实施工作的最新发展情况进行介绍。

1．美国联邦机动车安全标准（FMVSS）1966年9月，美国颁布实施《国家交通及机动车安全法》，授权美国运输部（DOT）对乘用车、多用途乘用车、载货车、挂车、大客车、学校客车、摩托车，以及这些车辆的装备和部件制定并实施联邦机动车安全标准（Federal Motor Vehicle Safety Standards.简称FMVSS）。

任何车辆或装备部件如果与FMVSS不符合，不得为销售的目的而生产，不得销售或引入美国州际商业系统，不得进口。

根据目前《国家交通及机动车安全法》最新修订本的规定，对违反此法要求的制造商或个人，美国地区法院(district court)最高可以处以1500万美元罚款的民事处罚，对造成人员死亡或严重身体伤害的机动车或装备安全缺陷隐瞒不报，或制造虚假报告的制造商将追究刑事责任，最高刑事处罚为15年有期徒刑。

在美国《国家交通及机动车安全法》的授权下，由美国运输部国家公路交通安全管理局具体负责制定、实施联邦机动车安全标准，它们都被收录在"联邦法规集"（Code of Federal Regulation, 简称CFR）第49篇第571部分。

FMVSS201规程在车辆内饰件与乘员头部碰撞中的应用

FMVSS201规程在车辆内饰件与乘员头部碰撞中的应用王亚军;陈超卓;吴沈荣【摘要】在发生车辆碰撞时,车辆内饰件要起到保护乘员的作用.该文利用1998年颁布的美国联邦机动车安全标准FMVSS201(FMVSS,为美国联邦机动车安全标准,Federal Motor Vehicle Safety Standards and Regulations的缩写),考虑到硬点、位置、内饰件材料、护钣厚度、加强筋等因素,建立了CAE(计算机辅助工程,Computer Aided Engineering)模型.对于护钣厚度、材料和结构三方面对内饰件碰撞的敏感性因素进行分析.用简化力学模型,分析了内饰件对乘员头部受力.分析方法可用于改进车辆内饰件的设计.【期刊名称】《汽车安全与节能学报》【年(卷),期】2010(001)002【总页数】5页(P127-131)【关键词】车辆碰撞;乘员保护;车辆内饰件;头部损伤【作者】王亚军;陈超卓;吴沈荣【作者单位】奇瑞汽车股份有限公司,汽车工程研究院整车安全部,芜湖市,经济技术开发区,41009;奇瑞汽车股份有限公司,汽车工程研究院整车安全部,芜湖市,经济技术开发区,41009;奇瑞汽车股份有限公司,汽车工程研究院整车安全部,芜湖市,经济技术开发区,41009【正文语种】中文【中图分类】U27众所周知,安全带、气囊等对乘员起到重要的保护作用,但是内饰件的吸能作用也不可忽视。

车辆内饰件就不能仅仅满足装饰作用,还要满足在一定工况下保护乘员的作用。

在前碰撞中,车辆碰撞分为车辆前结构碰撞障碍物的一次碰撞,以及车内乘员碰撞内饰件的二次碰撞。

1998年美国颁布了内饰件碰撞规程(FMVSS201)[1](FMVSS为美国联邦机动车安全标准,Federal Motor Vehicle Safety Standards and Regulations的缩写)。

该规程要求24 km/h碰撞时,车内乘员头部不得受伤。
