Abstract

CE PROCEDE EST CARACTERISE EN CE QU'A PARTIR DE LA POSITION DE DEPART ET DE LA POSITION FINALE DESIREE DU CHARIOT ET DU PALAN, AINSI QUE DES LONGUEURS DE PALAN MAXIMALES ADMISSIBLES PENDANT LE TRANSPORT, ON CALCULE A PLUSIEURS REPRISES POUR DIFFERENTES VALEURS D'ACCELERATION, EN UTILISATION LA LOI DE MOMENT D'IMPULSION: (CF DESSIN DANS BOPI) DANS LAQUELLE G ANGLE DE DEVIATION PAR RAPPORT A LA VERTICALE, Y POSITION DU PALAN, G ACCELERATION DE LA PESANTEUR ET X POSITION FINALE DU CHARIOT, LA DEVIATION RESIDUELLE DU PALAN EN POSITION FINALE, ON DETERMINE LES RESULTATS PAR COMPARAISON AVEC L'ACCELERATION POUR LAQUELLE LA DEVIATION RESIDUELLE EST MINIMALE ET L'ON ENVOIE LA VALEUR D'ACCELERATION MESUREE AU MECANISME DE COMMANDE DU PONT-GRUE.THIS PROCESS IS CHARACTERIZED IN THAT FROM THE DESIRED STARTING AND FINAL POSITION OF THE TROLLEY AND HOIST, AS WELL AS THE MAXIMUM PERMISSIBLE HOIST LENGTHS DURING TRANSPORT, WE CALCULATE SEVERAL TIMES FOR DIFFERENT ACCELERATION VALUES , USING THE LAW OF PULSE MOMENT: (CF DRAWING IN BOPI) IN WHICH G ANGLE OF DEVIATION FROM THE VERTICAL, Y POSITION OF THE HOIST, G ACCELERATION OF THE GRAVITY AND X FINAL POSITION OF THE TROLLEY, THE RESIDUAL DEVIATION OF THE HOIST IN THE FINAL POSITION, THE RESULTS ARE DETERMINED BY COMPARISON WITH THE ACCELERATION FOR WHICH THE RESIDUAL DEVIATION IS MINIMUM AND THE MEASURED ACCELERATION VALUE IS SENT TO THE CRANE BRIDGE CONTROL MECHANISM.
