In the extractive industry, single bucket hydraulic excavators are used to extract loads of material from silos or dumps, move and unload these on to the transportation means. Single bucket hydraulic excavators can also be used to make embankments and dikes, to dig foundations, ditches and roadbeds. Their operating performance, such as work space, technological forces, cutting and loading capacity, are closely related to the structure and operation, kinematics and dynamics of the bucket-arm mechanism, which can be assimilated with a spatial manipulator with 4 degrees of freedom (DoF). This offers the possibility to use the theory of manipulators, adapted to the specific destination of hydraulic excavators, in order to model and simulate them. For the simulation and study of kinematics in this paper, the Hyundai R30Z-9AK mini-excavator arm model was developed in the SOLIDWORKS® application. [ABSTRACT FROM AUTHOR] |
