摘要
通过统计分析乘用车与商用车的各种实际碰撞事故类型数据,证明了正面碰撞造成的乘用车乘员伤亡率最大。在正面碰撞中,为了防止乘用车钻入商用车前下部和保护乘用车乘员的安全,ECER93法规强制要求商用车安装前下部防护。通过分析商用车前下部防护法规ECER93的技术内容及其未来的提高方向,以及国外公司采用的典型设计结构可知,吸能型前下部防护是目前的研发方向。
Through statistical analysis of various types of crash data of passenger cars and commercial vehicles,it is proved that the frontal crashes caused the largest casualty rates of the crew of the passenger cars.In a frontal impact,in order to prevent passenger cars from underrunning the lower front part of commercial vehicles and protect the passenger＇s safety,regulation ECE R93 demands compulsorily all commercial vehicles to install underrun protection in the lower front part of vehlcle.It is concluded from the analysis of technical content and the future enhancing trend of regulations ECE 93 and the typical design structure of foreign companies.The energy-absorption＇s lower front part protections are the recent development trend.
