CRH3动车组塞拉门的安全可靠性

摘要

CRH3 EMUs sliding plug door is an important way to import the passenger trainset, the characteristics of the multi lip seal, multiple locking, high strength composite door leaf, has high sealing performance, can reduce the passenger compartment noise, heat insulation, ifre prevention function is very strong, long service life, protects the safety of passengers and the facilities in the bus function. When high speed train operation and import and the tunnel, the sliding plug door to bear the air pressure wave of powerful, sliding plug door frame and the door leaf ifxing device, and the ifxing device is provided with high strength and stiffness. Because of the great inlfuence of pressure lfuctuation in vehicle for passenger comfort, airtight door with high performance. According to the operation characteristics of high speed EMU, the design requirements of the door has high security and reliability.%CRH3型动车组塞拉门是旅客进出车组的重要途径，其特点多唇密封，多重锁闭，高强度复合门扇，具有很高的密封性能，可降低客室噪声，有很强的隔热、防火功能，使用寿命长，起着保护旅客及车内设施安全的作用。当列车高速运行和进出隧道时，塞拉门要承受强大的空气压力波，塞拉门门框及其固定装置、门扇和其固定装置具有很高的强度和刚度。由于车内气压波动对乘客的舒适性有很大影响，车门具有很高的气密性能。根据高速动车组的运行特点，车门的设计具有很高的安全性要求和可靠性要求。
