全路首创,对铁路行车安全有显著作用的“扩编旅客列车紧急制动电控装置”和“列车尾部风压监测装置”在广州局研制成功,并于5月28日通过局极鉴定。 扩编旅客列车紧急制动装置 它是吸取了国外电空装置的特点,结合我国铁路车辆空气制动实际研制而成的。每列车只需在列车前、中、后三辆车上各安装一个“电控装置”,与原制动机并联工作,只是在紧急制动时起作用。机车不需加装任何设备。该装置具有防止折角塞门关闭作用,当第二辆及以后任何一辆折角塞门被关闭时,全列车仍能起紧急制动作用。经西南交大所做的列车静置试验、运行试验和列车动力学模拟计算表明,当旅客列车扩编25辆时,在不延长制功距离的情况下,列车纵
The first of its kind in the railway, the “Emergency Brake Electric Control Device for Expanding Passenger Trains” and the “Wind Pressure Monitoring Device for Tail Train”, which have a significant effect on railway traffic safety, were successfully developed in Guangzhou Bureau and passed the Bureau Identification on May 28. Expansion of passenger train emergency brake device It is learned from the characteristics of foreign electro-pneumatic device, combined with the actual development of China’s railway vehicle air brake made. Each train only needs to install an “electric control device” on the front, middle and rear of the train, which works in parallel with the original brake, and only functions during the emergency braking. No need to install any locomotive equipment. The device has the function of preventing the cockpit from closing and the entire train can still serve as an emergency brake when the cockpit of the second and any other folds is closed. By the Southwest Jiaotong University train static test, the running test and train dynamics simulation show that when the expansion of passenger trains 25, without extending the working distance, the train longitudinal
