Vibration Environment Test and Standard Comparative Analysis of Urban Rail Train Key Parts
In order to test whether the vibration environment state of the train critical equipment during operation com-plies with the relevant standards,a vibration data acquisition and analysis system is constructed by using a three-axis acceleration sensor combined with multi-channel parallel acquisition devices and a PC,and the vibration tracking tests and records are completed for the five key components of encoder odometer,indexing arm,bogie,axle box,and torsion bar. The test results are compared and analyzed according to the national standard GB/T 21563-2018. Fi-nally,the evaluation of whether the force field stress of the operating condition environment of the vehicle equipment meets the relevant design standards is completed.
