摘　　要：为保障城市轨道交通的安全运营,需定期对车门夹紧力进行检查。本文根据车门障碍物探测功能的原理和行业标准对车门夹紧力的要求,设计了一种车门夹紧力测量装置,采用测力传感器作为参考标准,利用电机和导轨的机械运动实现不同关门位置、不同关闭距离下的车门夹紧力测量,并对测量结果的不确定度进行分析。In order to ensure the safety of city transit system,the clamping force of train door needs to be checked regularly.Based on the principle of the door obstacle detection function and the requirement for clamping force of train door from industry standard,the paper introduces the measuring device for clamping force of train door.The measuring device uses force transducer as reference standard,and it can measure the clamping force of train door at different door positions or different closing distance by utilizing the mechanical motion of electric machine and rail.The uncertainty of measurement was analyzed in the paper.
