ABSTRACT:
A deformation of a rotating tire on a road surface is calculated the following. At first, time series data of acceleration extracted from measurement data of acceleration corresponding to one round of tire rotation is subjected to a time integration of second order to obtain displacement data so as to calculate the deformation at the tread portion. The time series data of acceleration and the displacement data in the non-contact region excluding a road surface contact region on the tire circumference at the tread portion are respectively approximated to calculate a first and a second approximation curves. The two approximation curves are subtracted respectively from the time series data of acceleration and the calculated displacement data, thereby extracting time series data of acceleration due to tire deformation and obtaining the deformation at the tread portion.
