【摘要】：商用车在世界各国的经济发展中发挥着越来越大的作用,其在我国已成为最主要的交通运输工具。由于自身的尺寸、车身质量相对较大,一旦发生交通事故,通常会造成交通参与者的人身伤害和车辆及公路设施的损毁,是造成恶果的交通事故形态之一。目前在我国因商用车造成的交通事故死伤数量也取代乘用车位居第一。因此,如何减少交通事故造成的伤害,最大限度地保证交通事故中交通参与者的安全,提高商用车的安全性,具有重要的现实意义。本文以商用车被动安全结构(乘员保护结构、前/后下部防护装置)作为研究对象,解读了世界主流标准法规体系对商用车被动安全性的技术要求,总结了我国标准与欧洲法规对商用车被动安全结构性能要求及试验方法的差异,设计开发了用以解决商用车被动安全性结构检测和试验的试验检测系统;通过实车试验结果的统计,产品质量状况分析判定,对产品安全性能的优化改进和标准法规的制、修订提出合理化建议。
[Abstract]:Commercial vehicles are playing a more and more important role in the economic development of all countries in the world, and they have become the most important means of transportation in our country. Because of its own size, the quality of the body is relatively large, once a traffic accident occurs, it will usually cause personal injury to traffic participants and damage to vehicles and highway facilities, which is one of the forms of traffic accidents that cause bad results. At present, the number of traffic accidents caused by commercial vehicles in China is also the first to replace passenger cars. Therefore, it is of great practical significance to reduce the injury caused by traffic accidents, to ensure the safety of traffic participants in traffic accidents to the greatest extent, and to improve the safety of commercial vehicles. In this paper, the passive safety structure of commercial vehicles (occupant protection structure, front / rear lower protective device) is taken as the research object, and the technical requirements of the world mainstream standard and regulation system for the passive safety of commercial vehicles are interpreted. This paper summarizes the differences between Chinese standards and European regulations on the performance requirements and test methods of passive safety structure of commercial vehicles, and designs and develops a test and testing system to solve the problem of passive safety structure testing and testing of commercial vehicles. Through the statistics of the test results of the real vehicle and the analysis and determination of the product quality, the reasonable suggestions are put forward for the optimization and improvement of the safety performance of the product and the system of the standards and regulations.
