乘用车顶部抗压强度试验及发展趋势

摘要

As death rate of rollover is very high in traffic accident, aimed at improving protection peffomlance of vehicle when rollover happens, with full consideration of Chinese conditions, GB 26134-2010 ＂Roof Crush Resistance of Passenger Cars＂was released officially on 14th Jan of 2011. The preparation and implementing process and requirements of body strength test was determined. In this paper test method specified in GB standard was introduced, preparation and implementation process were described in detail. The trend of roof crush resistance standard was proposed based on analysis of U.S. Federal Motor Vehicle Standards FMVSS 216a.%由于交通事故中侧滚翻事故的死亡率非常高，为达到车辆发生侧翻时对乘员的保护，充分考虑我国国情，2011年1月14日，我国正式发布GB26134--2010《乘用车项部抗压强度》国家强制性标准，明确对车身强度试验的准备和实施过程及要求，文章以标准规定的试验方法为主要内容，详细介绍了试验的准备和实施过程，并结合美国联邦机动车法规FMVSS216a提出了汽车顶部抗压强度法规的发展趋势。
