Abstract
The purpose of this project was to derive a mathematical model which could describe the complete operation of a Marion Type 7800
dragline. This model could then be used for subsequent optimization studies leading perhaps to the fully automatic control of the digging
operation.
The dragline electrical equipment consisting of rototrols, generators and motors was, simulated on an analogue computer. The resulting
steady state operations agreed very well with those of the actual dragline. Accurate definition of the load motion was difficult due to its
highly nonlinear nature. Simulation of the nonlinear motion was made possible by the use of relays which altered the operating conditions as
the analogue dragline cycle progressed.
The results obtained indicate that a mathematical analysis, aided by an analogue computer, could be used to study dragline performance.
