Summary

 
Object and purpose of research.Coaxial current-carrying elements are parts of numerous electric equipment, including transformers, reactors and various electric machinery characterized by inductance parameters and electrodynamic interaction. This paper studies thin-layered rectangular and cylindrical coils of loading devices intended for bollard-pull testing of heavy-duty marine gensets. The main purpose of this study is to analyse and calculate electrodynamic forces arising in solenoids of loading devices, to take design measures for preventing possible damage during the tests that are a compulsory part of mooring tests for electric power plants of ships
Subject matter and methodsThe assessment of electrodynamic forces is based on the calculation of mutual inductance in the selected structure. The forces on extreme coils of solenoids are determined using special functions.
Main results.Main results are the assessment of the forces to be taken into account in decision making on the design of loading device solenoids.
Conclusion.The results of this study could be also used for other similar applications.
