中美轮胎特保案引起轩然大波,全世界的目光都在着注视这一事件的动态与发展——9月11日,美国总统巴拉克?奥巴马决定对中国输美轮胎征收紧急关税,加剧了日渐熟悉的中美贸易论战。这是奥巴马执政以来在贸易政策方面作出的首个重大决定,此举不仅给正值巅峰的中美关系带来严峻挑战,而且为9月21日在美国匹兹堡举行的二十国集团(G20)领导人第三次金融峰蒙上一层阴影。这对正在恢复中的全球经济来说,无疑是个坏消息,将构成严峻挑战。
事隔一天,中国也启动一项审查程序,以调查美国肉鸡和汽车部件是否在中国市场进行不公平的倾销,中美轮胎特保案让黝黑的轮胎成为阻碍中美经济发展的“大球”。 相似文献

就在奥巴马忙于应付中国输美轮胎特保案成立之后所引起的一系列“麻烦”之际,9月16日又颁布了针对2012年至2015年车型的油耗和二氧化碳排放标准,要求汽车生产商产品的平均燃油耗在2016年之前达到35.5mile/gal(6.16L/100km)的国家标准。 相似文献

尽管2008年金融危机席卷全球,不少轮胎企业纷纷倒闭或停产;尽管中国输美“轮胎特保案”使得夹缝中生存的中国轮胎业陷入更加窘迫的困境,但第七届中国国际轮胎博览会仍然于9月8日至10日在上海光大会展中心如期召开,有230家经历了金融危机打击和考验的轮胎企业积极参展,借展会契机谋略新的商机。 相似文献

看起来这是一个出乎意料之外的美国政府决定。因为在此之前,基于双方政治经济关系发展良好,关于中国输美轮胎特保案的前景,中美业界均呈现了相当的乐观氛围。 相似文献

9月5日,悬了两年,由美国制造的“轮胎特保案”终于落停。世界贸易组织一份123页的终审裁决,再度将中国汽车零部件产业推向了尴尬的局面,终审判定美国对中国输美轮胎征收惩罚性关税符合世贸规则,这就意味着始于2009年6月,由奥巴马提出的对中国出口到美的乘用车与轻型卡车轮胎连续2年分别加征55%、45%的关税之后,明年还要征... 相似文献

近年来,我国汽车产销量直线上升,已超越美国成为世界第一大汽车消费市场,但随着汽车保有量的增长,汽车爆胎事故也在不断上升,已严重威胁人民群众的财产和生命安全,据公安部统计,高速公路70%的亡人交通事故是由于爆胎引起的,汽车时速在120公里发生爆胎,死亡率为100%.因此,如何预防和减少汽车爆胎,已经成为汽车安全的焦点话题,那么汽车爆胎的原因是什么呢?遇到爆胎怎么办呢?如何有效地预防汽车爆胎呢? 相似文献

Based on the modeling of tire vertical characteristics and steady cornering properties, the model of tire nonsteady cornering is established in this paper using tire modal parameters extracted experimentally. In order to consider the influence of tire rolling effect on its cornering properties, the induced transfer function is introduced. The analytical formulae for calculation of transfer-function of lateral force and self-aligning torque with respect to lateral displacement and yaw angle are derived. The nonsteady cornering characteristics of tire under different loads can be calculated. The results of calculation are consistent with the experimental ones in the literature. The influence of rolling speed on tire cornering properties including the static case is analyzed. The nonsteady cornering properties in high frequency range are given by the model. The study demonstrates the consistency between steady and nonsteady tire modeling by using modal parameters. 相似文献

In the dynamic simulation of vehicle straight line motion, a vehicle model usually drifts from its intended straight path even in the case of no external input. This is particularly true when a tire model based on experimental data is used. The purpose of this paper is to provide an enhancement of a basic understanding of a tire/vehicle system behavior in the straight line motion and to identify the effect of the tire on that motion. Through the analysis of a two degrees of freedom vehicle model, tire characteristic which causes a lateral drift in the straight line motion is identified. Then the results are confirmed from vehicle test and the simulations with a more complex full-car model. 相似文献
