| description | L'invention concerne un procédé et un appareil pour mesurer la portance d'un e plateforme (10) d'infrastructure de transport et sols industriels. L'appareil comporte une roue (2) portée par un châssis (3) mont é oscillant sur une remorque (4) tractée par un véhicule (9). Un balourd (l3) fait vibrer la roue (2). On mesure en continu l'accélération verticale du châssis (3) et de la roue (2) et l'angle de la force centrifuge du balourd avec la verticale. On calcule la force totale appliqué e par la roue (2), le châssis (3) et le balourd à partir des mesures des accélérations, et la déflexion de la plateforme (10) par intégration double de l'accélération de la roue (2).
The invention relates to a method and an apparatus for measuring the lift of a transport infrastructure road level and industrial floors. The apparatus comprises a wheel borne by a chassis pivotally mounted on a trailer towed by a vehicle. An unbalanced member causes the wheel to vibrate. The vertical acceleration of the chassis and of the wheel and the angle of the centrifugal force of the unbalanced member with the vertical, are continuously measured. The total force applied by the wheel, the chassis and the unbalanced member is calculated from the measurements of the accelerations, as is the deflection of the road level by double integration of the acceleration of the wheel. |
