@ARTICLE{Ocioszyński_Jerzy_Energy, author={Ocioszyński, Jerzy and Majewski, Przemysław}, volume={vol. 48}, number={No 4}, journal={Archive of Mechanical Engineering}, pages={301-317}, howpublished={online}, publisher={Polish Academy of Sciences, Committee on Machine Building}, abstract={The Authors present the problems of theoretical analysis and experimental research related to the possibilities of energy recovery in selected phases of operating and running cycles of self-driven crane. Heavy machinery powered by diesel engines is a source of solid toxic emissions. In order to limit these emissions, one install filters and filter regeneration systems. According to the concept presented here, the recovered energy might be utilised for regeneration of these filters by burning off accumulated solid particles (soot). Mechanical energy would be the power source to drive DC generators - the mechanical-into-electric energy converters. Filter's heating resistors, acting as the generators' load, would radiate a power of 3-;-5 MJ to initiate burning of soot in the filter. The calculations of energy consumed during sheave block lowering phase were made for three different lifting capacities taking into account the boom length and crane reach. Three running cycles of the crane: highroad, urban and off-road ones were also analysed. The time functions of variations of crane running speed and power of motion resistance at driving wheels were found. The results provided the background for determination of theoretical values of energy to be regained during braking phase of the analysed cycles. The structure and operation of experimental stands was discussed. The stands contain units that, at proper size factor, represent the processes that occur in real cranes and that are related only to energy recovery. Computer software for system simulation, control and measurement was described. Measurement results and result analysis are presented. The value of energy found theoretically was compared with the energy recovered during experimental tests. The paper also contains simplified kinematic schemes of selected units of crane lifting and driving systems, including an additional DC generator. This concept, however, needs verification in future design solutions.}, type={Article}, title={Energy recovery for reducing toxic exhaust emissions in selected energetic states of individual operating cycle in self-driven heavy machinery}, URL={http://journals.pan.pl/Content/125342/PDF/3_MECHANICAL_48_2001_4_Ocioszynski_Energy.pdf}, keywords={energy recuperation, self-driven crane, heavy machinery, running cycle, operating cycle, energy recovery}, }
