Algorithm of Energy-Saving Control Over Hammers of Active Excavator Buckets

The article considers the operation of excavators designed to mine hard or frozen soils. To reduce significant energy consumption, which characterizes process, active buckets equipped with special hammers are used. Minimizing consumption such can be achieved by optimally controlling their operating modes. Expressions for consumed a hammer, characteristics its head, modes, soil derived, minimum estimated. On basis those expressions, an algorithm energy-saving control over excavator is formed and described. It determines corresponding speed impact hammer head on supplied system in form command signal. combination all speeds when digging track will provide required performance excavator, each set minimum, from viewpoint optimizing necessary work hammer.
