Tire-axle-force measuring apparatus

A tire-axle-force measuring apparatus comprising:

• a trailer to which testing tires are attached;
• a towing vehicle configured to tow the trailer;
• and
• a load cell configured to measure an axle force applied to an axle supporting the tire,
• the tire-axle-force measuring apparatus further comprising:
• a heavy construction to each of two sides of which the load cell is fixed, the two sides being located opposite each other in a vehicle width direction;
• an accelerometer attached to the load cell at a position close to the axle and configured to measure an acceleration acting on an axial center of the axle;
• and
• an axle-force calculator configured to calculate a revised axle force compensated for with an inertial force, the inertial force being the acceleration detected by the accelerometer and multiplied by a mass of the load cell at the position close to the axle, the revised axle force being the sum of the axle force measured by the load cell and the inertial force.
