Abstract
In the paper, the kinematic structure of the transmission shaft between the driving motor and the working mechanism is studied. The analysis is based on electrical and mechanical similarities. The equivalent circuits, typical for electrical systems, are defined for the transmission shaft concerned. Modelling of the transmission shaft based on a formal analogy between the transmission shaft and the electric transmission line is also proposed. The results of a computer simulation and experimental test are presented. The results confirm the high conformity of the proposed mathematical model with the physical object.
Highlights
Rapid development and diversity of electric drive systems require extensive theoretical and practical knowledge as well as the use of a wide range of theoretical and constructional solutions from the contemporary designers and users
Electric drive systems are used in all branches of industry; the trouble-free operation of these systems is of crucial importance
High accuracy of the proposed model goes hand in hand with its simplicity and, as a consequence, with a short time of numerical calculations in contrast to the modelling based on numerical integration of differential equations or analytical solution of partial differential equations
Summary
Rapid development and diversity of electric drive systems require extensive theoretical and practical knowledge as well as the use of a wide range of theoretical and constructional solutions from the contemporary designers and users. Electric drive systems are used in all branches of industry; the trouble-free operation of these systems is of crucial importance. An analysis of the states of electric drive operation is often related to ensuring its safety. Ignoring the analysis and the ongoing diagnostics of vibrations in electromechanical systems results in many failures. The example, including fatalities, is inter alia the failure of turbo generator set in the power plant Kostromska (Russia). The cause of the failure was ignoring torsional vibrations, which led to the resonance in the turbine and transmission shaft included in the turbo-generator set
