Abstract: Electromagnetic clutch is a core component of mechanical transmission systems, and its electromagnetic force characteristics directly determine the response speed and control accuracy of the transmission system. This paper adopts ANSYS Electronics software to carry out simulation analysis on the electromagnetic force of electromagnetic clutches, and investigates the error law between electromagnetic force simulation and actual measurement. It first expounds the structural composition and working principle of electromagnetic clutches, and clarifies the generation mechanism and action transmission path of electromagnetic force. Secondly, it establishes a twodimensional finite element model of the electromagnetic clutch, sets material properties, excitation loads and boundary conditions, and completes the construction and parameter assignment of the simulation model. Simulation calculation obtains electromagnetic force distribution nephograms under different working conditions, and analyzes the variation characteristics of electromagnetic force on key components. Error analysis is conducted by comparing simulation and measured data, and the overall error is controlled within 10% to effectively guarantee the reliability of the simulation model. The research results can provide theoretical basis and technical reference for structural optimization design and engineering practical application of electromagnetic clutches.
