Abstract: In a detecting apparatus, a resolver generates signals whose magnitudes vary periodically in accordance with a positional change of a fixed element side rotating shaft, which is a base for rotation of a rotator and whose position is offset when force of a component parallel to a rotation plane is applied thereto, and in accordance with a rotational state of the tire. An R/D converter generates pulses whose periods correspond to a rotational angle of the rotator and to positional offset of the rotating shaft. From the pulses, a computer detects a characteristic amount which varies in accordance with the positional offset of the shaft. On the basis of the detected amount and a relationship which is determined in advance on the basis of stiffness of the shaft and the amount, the computer detects a moment applied to the shaft, and computes a force generated at the tire.

Abstract: A multi-axis force platform for determining forces and moments exerted on the platform along x, y and z axes includes at least one multi-axis spring. The multi-axis spring includes a block of rigid material through which a pattern of slots pass through to form a series of deflectable beams separated from each other by the slots. The deflectable beams surround an interior region of the spring and elastically couple the interior region of the spring to an outer region of the spring such that the interior region can deflect relative to the outer region along x, y and z axes when subjected to a load. One or more magnetic sensors are positioned within the interior region of the spring for sensing loads exerted on the spring.
