站台与列车间空隙缩小试验分析

通过对站台与列车间空隙的现状调查、车辆限界的分析和标准规范的解读，提出缩小该空隙的必要性和可行性。以Bombardier公司供货的深圳地铁车辆为例，运用车辆动力学模拟的限界计算结果进行站台空隙缩小试验。理想的站台空隙仅满足实际车辆限界的要求，行车安全空隙利用齿形橡胶填充为柔性间隙，在确保行车安全的同时使乘客上下车更安全．

On Reducing the Gap between the Train and the Platform Edge

The neccesity and feasibility of reducing the gap between the carriage and the platform edge is put forward by analysing the current gap and the clearance-gauge of vehicles as well as the recognition of national standards. Utilizing the trains supplied by Bombardier Co. in Shenzhen metro, gauging analysis have been carried out by means of vehicle dynamic simulation. Results of the dynamic vehicle profiles are tentatively adopted to reduce the current gaps. The ideal platform gap can only satisfy the practical vehicle profile, and the safety gap for train motion should be filled with a flexible saw- toothed rubber Idler to guarantee simultaneously the safety of operation and the safety of passengers boarding and alighting the train.
