Equations of electrodynamic similarity of electrically driver trawl winches
This article reviews the equations of electrodynamic similarity of trawl winches having an electric drive with independent excitation. The criterion equations are essential for determining the power parameters of structural members for trawl winches, which have different technical attributes, which significantly complicates the theoretical analysis during their design and modeling. An essential component of the electrodynamic similarity is preservation of the physical nature of the original phenomena in a model made in dimensions different from the actual ones. In electrodynamic problems, it is required to ensure the similarity of mechanical, electrical and electromagnetic processes. It is necessary to characterize the force interaction of the object and the environment with dimensionless quantities. When designing and modeling trawl winches with an electric drive, the scale of the physical attributes of hydrodynamic, soil-dynamic and tribological processes occurring with fishery equipment under dynamic similarity is insufficient, since they do not take into account the electrodynamic processes occurring in the fishery machineries.
