Research for reduction material-capacity of load-lift cranes with multi-engine electric drives on the base electromagnetic work shaft systems

Abstract

This work is devoted to the study of multi-machine systems of coordinated rotation of the engines of handling equipment. The purpose of the work is to identify, by theoretical calculation, the reduction in the metal consumption of cranes equipped with multi-motor electric drives and operating on the principle of an electromagnetic working shaft, in comparison with the current ones. The analysis of the shifting moments of these systems in dynamics was made and conclusions were drawn about the reduction in the weight of the metal structures of cranes and the saving of metal in their production.

Analysis of metrological supply problems in electricity generation

“…Due to the small size of systematic errors, systematic measurement error can also be reduced by multiplying the measurement findings by a correction factor that is close to the average value. It is expected that during the inspection of measuring instruments, correction and correction factors are predetermined [25][26][27][28][29]33].…”

“…As a result, traditional components will gradually be largely replaced by metrological self-monitoring inside the metrological supply. Regular metrological processes will take less time, but there will be more demand for highly skilled metrologists to work on developing new measuring instruments [26][27][28][29][30][31].…”
