Abstract: Denavit-Hartenberg notations were used to study the forward and reverse kinematics of an excavator performing the fine finishing pass of a trenching operation. An approximated path generation technique was developed. A hydraulic control system with proportional values was modelled and simulated with proportional and proportional-integral control using the EASY 5/W simulation language. The simulation results illustrate the approximate performance which could be expected during flat-bottom trenching with light loading.
Keywords: automatic control; excavators; excavator kinematics; hydraulics; hydraulic control; simulation; trenching operations.
