摘　　要：文章通过对时速80 km地铁B型车进行空气动力学现场试验,得到该速度等级下车内空气压力的变化情况,并分别采用TB/T 3503.3-2018和CJJ/T 298-2019两种标准对耳压舒适度进行评价。结果表明,时速80 km地铁B型车在避开风井位置的隧道中运行时,司机室和客室的压力变化幅值均满足两种标准的相关要求;但该列车在通过中间风井位置时,司机室和客室的压力变化幅值不能完全满足CJJ/T298-2019标准的相关要求,因此需对风井结构进行优化。In this paper, the aerodynamic field test is carried out on the 80 km/h B-type metro train, and the change of air pressure in the train at this speed level is obtained. The two standards of TB/T 3503.3-2018 and CJJ/T 298-2019 are used to evaluate the ear pressure comfort. The results show that when the 80 km/h B-type metro train runs in the tunnel avoiding the ventilation shaft, the pressure change amplitude in the cab and saloon meets the relevant requirements of two standards. However, when the train passes through the middle ventilation shaft, the pressure change amplitude in the cab and saloon cannot fully meet the relevant requirements of CJJ/T 298-2019, so the structure of ventilation shaft needs to be optimized.
