摘　　要：针对现有中分带开口活动护栏存在的问题,提出了活动护栏设计新理念,并设计由快速开启段、可开启段和端部过渡段组成的具有快速开启功能的新型防撞活动护栏方案,建立经实车碰撞试验验证的有限元仿真模型对活动护栏的安全性进行评估。试验结果表明活动护栏的阻挡功能、导向功能和缓冲功能均满足评价标准要求,防护等级达到Am级。Based on the current situation of moveable barriers,the author gave the new idea for moveable barriers design,and the new design scheme of moveable barriers which consist of rapid opening segment,the structure of opening segment and transition segment was designed.The safety performance of barriers was evaluated by building computer simulation models which were verified using full scale crash tests.The results show that the containment performance,the buffering performance,and the redirective performance meet the evaluation standard requirements,protection level of barriers achieved Am-level crash rating.
