Dynamic Responses of the Metro Train's Bogie Frames: Field Tests and Data Analysis
Shock and Vibration
This paper focuses on the dynamic characteristics of the metro train's bogie frames based on the field test data. The acceleration signals of both motor bogie frame and trailer bogie frame of a standard B-type metro train were measured. Running tests on the Metro line 21 of Guangzhou (China) were carried out. The acquired acceleration signals of bogie frames were analyzed through several methods to identify the dynamic characteristics of the motor and trailer bogies in the time-frequencydoi:10.1155/2020/1484285 fatcat:cva3p4wozrawdnhcdgt5jtgdjy
