Imitating modeling results of a recuperative hydraulic subsystem of the timber truck manipulator

Abstract

Abstract The relevance of improving the efficiency of a timber truck used for timber transportation due to the use of a recuperative hydraulic drive in its design is substantiated. The analysis is made of the use of recuperative hydraulic drives of technological machines with mechanisms for the recovery of kinetic energy of rotation and potential energy of lowering the load. A mathematical and, based on it, simulation model has been developed for the hydraulic subsystem of the manipulator of a timber truck, including mechanisms of boom, handle and column recuperation that have also been developed. Dependencies are obtained that make it possible to determine the maximum amount of recuperated energy for one loading cycle by changing the volume of the pneumohydraulic accumulator, the height of the assortment, and the time of one loading cycle.
