Abstract

To validate vibration test method of ISO 12405 for electric vehicles, we developed vibration test conditions, Power Spectrum Density (PSD) and test duration, using three electric vehicles under the assumption that these vehicles travel Japanese road. The PSDs were calculated from the chronological order data of acceleration obtained while running the vehicle according to each sub scenario. The developed test PSD indicated that the PSDs in ISO 12405 are validate. However, test duration of ISO 12405 for each axis doesn't validate, because calculated test duration for the X and Y axes in ISO 12405 are excessive, and for the Z axis is a bit short. Furthermore, in road environment other than Japan, the test durations of the X and Y axes does not exceed the test duration for the Z axis. Therefore, the test durations for the X and Y axes in ISO 12405 should be shorter than the test duration for the Z axis.
