Modelling and simulation of a miniaturised actuating solenoid device

摘要

The main objective of this paper is to present a computer based design model of a miniaturised actuating solenoid device capable of simulating the tripping of mechanisms under a range of loading conditions. In this work, the solenoid was applied in a VCR. The purpose of a solenoid is to activate the mechanism at the supply tape end and take-up end. This new technology has been developed using the Maxwell 2D and 3D Field Simulator and EMSS (Electromechanical System Simulator). The Maxwell 2D and 3D Field Simulator was used to develop an accurate, 2D and 3D representation of magnetic field behaviour needed for accurate modeling of solenoids. The EMSS enabled a fundamental analytical description of the device and accurate prediction of the performance of control system components. The miniaturisation approach presented here includes aspects of material selection, design parameters of permanent magnets, optimisation of geometric plunger shapes, and positioning of solenoid components. Particular emphasis is placed on DC solenoid modelling.
