铁路客车耐碰撞车体结构研究 杜彦品，陈海俊，李华丽，朱 亮 （南车南京浦镇车辆有限公司客车设计部，江苏南京 210031 ） 摘要：铁路客车仍然是乘客出行的主要工具之一。随着铁路客车的高速发展，乘客对车辆的行车安全提出了更高 的要求。我国铁路客车在主动安全方面有系统的措施，在车体被动安全防护方面还不成熟，近几年随着高铁时代 的到来，被动安全防护技术引起高度关注，现已成为铁路客车设计研究的一个热点。大多数国际项目对车体的碰 撞吸能也有明确要求，铁路客车车体被动安全技术显得非常必要和迫切。本文阐述了铁路客车耐碰撞车体的设计 理念及参照评价的设计标准，结合某具体项目详细介绍了耐碰撞车体的设计思路及车体结构，根据EN15227 标准 附录D.4 单节客车的碰撞工况，对耐碰撞车体进行CAE 碰撞计算及分析，论证铁路客车耐撞性结构设计的合理性。 关键词：铁路客车；耐碰撞车体结构；碰撞计算及分析 Research on Collision Resistance of Railway Passenger Carbody Structure DU Yanpin, CHEN Haijun, LI Huali, ZHU Liang (CSR Nanjing Puzhen Rolling Stock Ltd., Nanjing 210031, China) Abstract: Railway passenger cars is still one of the main tools of passengers. With the rapid development of railway passenger cars, higher requirements of vehicle driving safety is put forward. Railway passenger cars in our country have measures in the active safety, but the vehicle passive safety aspects are not mature. In recent years, with the High-speed Rail era, the passive safety protection technology caused great concern, and has become a hot research in the design of railway passenger car. Most of the international project on the body of the collision energy absorption also have specific requirements. The passive safety technology of railway passenger car body is very necessary and urgent. Design concepts of railway passenger car body of the collision resistance and design standard reference and evaluation is described in this passage. Combined with a specific project , the design ideas and body structure crashworthiness of car body is introduced in detail. According to the EN15227 standard
