Abstract
A method of estimating an eccentric position of an acceleration sensor for a double turntable-type acceleration generating apparatus includes the steps of mounting the acceleration sensor on an auxiliary rotating body; rotating the auxiliary rotating body at a constant frequency with a main rotating body held at a standstill; measuring an output signal from the acceleration sensor; determining an amount of eccentricity in an X-axis direction of the acceleration sensor from the frequency of the auxiliary rotating body and the output signal; and determining an amount of eccentricity in a Y-axis direction by using tangential acceleration generated by the rotation of the auxiliary rotating body in a state in which the amount of eccentricity in the X-direction is set to substantially zero.
