Dynamic model lifting-and-shifting machines battery powered

The growth of power consumption of lifting-and-shifting machines under transient modes demands the creation of mathematical models and on their basis the development of recommendations to improve the efficiency. Undoubtedly, the reasons for decrease in the lifting and shifting machines efficiency are changes of speed and load, which deviation from the optimum value causes the growth of energy losses. The other reason for the energy losses growth is the process of compulsory braking of these machines along with the loss of kinetic energy while retarding. The developed mathematical model allows to model the characteristics of lifting and shifting machines with hybrid power plants and to develop recommendations for machines with a flywheel energy accumulator by choosing the optimum gear ratio during braking energy recuperation.
