Abstract

An electromagnetic actuator as a source of motion is proposed and analysis is done to accomplish fatigue analysis, static structural analysis, and dynamic stability analysis of the electromagnetic actuator shaft. As the shaft is responsible for the sole transmission of generated electromagnetic force, it is the most important of part actuator which should be simulated in preliminary designed phase. As the shaft of the actuator is a ferromagnetic material the simulation shave been performed considering high frequency and high temperature environment to analyze its dynamic responses. As our proposed actuator is a linear or rotary actuator so according to that the actuator is designed and so shaft. As per the desired requirement the shaft will be subjected to axial or torsional excitations. Hence the stresses and deformations induced due course of motion in the component need to be studied in detail. Hence the shaft is designed in solid-works by assuming some geometrical feature i.e. suitable for both linear or rotary motion. Then simulation is performed in ANSYS WORKBENCH15.0to find the optimum shape and size of shaft which can resist the amount of load (force and torque) under high frequency and temperature environment. Finally, the dynamic stability of the shaft subjected to axial periodic forces is studied by the finite element method by using Euler-Beamtheory and Bolotin’s method. The dynamic instability plots for various shapes of shaft have been plotted to find the stable frequencies in operating range. The results show that in increment shaft diameter its stability improves
