Vibration Test and Analysis of HXD1 Electric Locomotive
To obtain the vibration characteristics of the electric locomotive from wheel-rail to traction converter,a vibration test has been carried out on the HXD1 electric locomotive on the railway line Huaihua-Zhangjiajie and its vibration characteristics have been analyzed in the conditions of waiting,constant-speed climbing and constant-speed running from the time domain and frequency domain according to the requirements of the standard GB/T 21563-2018.The study result shows the following:the vibration impact on the electric locomotive comes from the wheel-rail impact,the carbody impact and the contactor impact and the lower suspension system has a good antivibration effect against the wheel-rail impact;the power module inside the traction converter is mainly affected by the electromagnetic vibration of the capacitor,the effective values of vibration in three directions exceed the standard value and the vertical impact peak value exceeds the standard value;the fan of heat exchanger is mainly affected by the installation foundation and the effective value of lateral vibration exceeds the standard value.The data of vibration test on actual railway lines and the analysis result may provide a data basis for subsequent reliability study and structural optimization design of the vehicle-borne equipment.
