The displacement of the excavator bucket on the optimum trajectory through the control of the hydraulic cylinders lengths
Keywords:
hydraulic excavator, bucket position control, hydraulic cylinders, length magnetostrictive sensorsAbstract
The article refers to the hydraulic excavators with backhoe attachment equipped with length sensors at the hydraulic cylinders. The relations for the calculus of the lengths of the hydraulic cylinders of the excavator corresponding to a given position of the bucket cutting edge are established. These relations are necessary for the indication of the bucket position in the excavator cabin as well as for the automatic command of the working equipment of the excavator for obtaining an optimum trajectory of the bucket. An application for a concrete case was realized.
