METHOD FOR ANALYZING VIBRATION OF VEHICLE, AND DEVICE FOR ANALYZING VIBRATION OF VEHICLE

摘要

Provided is a vibration analysis technique using vibration measured as a vehicle travels on an actual road, the vehicle vibration analysis technique being capable of distinguishing various forms of vibrational input and detecting a vibration characteristic. In this vibration analysis technique, a vehicle is caused to travel on a road surface, the height of which shifts at various wavelengths along the direction of progress of the vehicle, and a transfer function is computed for a vibration characteristic values at locations of a vehicle body corresponding to at least two vibrational input values as partial regression coefficients by multiple regression analysis, using vibration characteristic values at locations of the vehicle body measured during travel as target coefficients, and using at least two vibrational input values that give rise to the vibration characteristic values as explanatory variables.
