<p>The invention concerns a method and an apparatus for measuring the load bearing capacity of a infrastructure platform (10) for transport and industrial floors. The apparatus comprises a wheel (2) borne by a body (3) mounted oscillating on a trailer (4) pulled by a vehicle (9). An unbalance (13) causes the wheel (2) to vibrate. The method consists in: continuously measuring vertical acceleration of the body (3) and the wheel (2) and the angle of the centrifugal force of the unbalance with the vertical; calculating the total force applied by the wheel (2), the body (3) and the unbalance from measurements of the accelerations, and the deflection of the platform (10) by double integration of the wheel (2) acceleration.</p> |
