We consider the nonlinear iron reluctance and leakage flux of the dispersion, the use of magnetic circuit established by the electromagnet differential mathematical model simulation using Matlab platform,<a href="http://www.toryburchbootss.com" target="_blank" class="postlink">tory burch boots</a>, the dynamic characteristics of the model to obtain the response of the simulation results with experimental The results were compared. 4.1 The mathematical model based on Kirchhoff's first law of magnetic circuit and flux continuity theorem, we can derive the following circuit equations: 』etc ... x l + Hc A / where: the magnetic flux, A guide for the unit of magnetic flux leakage, U for the core and yoke at the corresponding Y d), the pressure drop between the magnetic, H, and H is the same cross-section column and a yoke of iron core magnetic field strength, / as the unit length of the magnetic core formula. According to Ampere's law, the establishment, including the working air gap flux of the magnetic potential balance equation is as follows: iN = 6 / A + Hl + g / Ag + ΣHql + Hcilci + + J. (+ C) d), (2) where: i is coil current, Ⅳ number of turns,<a href="http://www.uggs-bestellen.org" target="_blank" class="postlink">uggs bestellen</a>, as the permeability, h is the coil height, Hz magnetic pressure drop for the segment. Maxwell suction formula F = x where: F is the electromagnetic suction, S is the area. Is the vacuum permeability. According to the voltage balance equation and Newton's laws of motion are obtained the equations of motion pull-keeper (4) and the release of the equations of motion (5). (4) (5) where: for the flux, U is voltage, R is the coil resistance, R is the coil circuit resistance, the armature speed, F, for the spring reaction force, m is the armature mass, the armature displacement. . f0,<a href="http://www.columbiasportswearoutlets.org" target="_blank" class="postlink">columbia sportswear outlet</a>, touch the stage l1, sports stage flux balance equation is: = Sri Lanka (6) (continued on page 7<img src="http://picsrv.fora.pl/images/smiles/icon_cool.gif" alt="Cool" border="0" />, J ~, £ £ d-~ a ~ ¨ iv one thousand one hundred and eleven x A x F ==== == a one hundred and eleven iv vii ... one ... one hundred and eleven of a aerospace control ~ * 78 * 2008 (on the next page 70 l4.2 mathematical model for calculating the dynamic characteristics of electromagnetic systems for solving the magnetic differential equation means that , the voltage balance equation and the d'Alembert equations of motion. taking into account the leakage flux and magnetic dispersion of the nonlinear case,<a href="http://www.uggboots-jp.org" target="_blank" class="postlink">UGG ブーツ</a>, using numerical methods, we use a fourth order Runge Kutta method. solve the equation of state group (4) and equations (5) the process, will inevitably encounter and the solution of the electromagnetic coil current i F suction problem, and F,<a href="http://www.uggsbotas.com" target="_blank" class="postlink">ugg botas</a>, and i was u,, m, and under the conditions gave, the function . using Secant method to solve equation (2) and (6) can be transformed into the known displacement of the flux and the armature coil current i and for solving the armature suction problems. 4.3 Simulation results Figure 6 is the dynamic characteristics of electromagnet simulation and test results graph, the result can be seen from the figure in good agreement. 5 Conclusion Based on the characteristics of electromagnetic servo drive design and testing of the corresponding device, the dynamic characteristics can be measured steering gear, which can test the rudder machine's performance. establish a mathematical model of solenoid actuator and its dynamic characteristics simulation and analysis consistent with the actual results for future optimization of the performance steering gear provides a reference. This system has been successfully applied in the performance testing of steering gear, use good effect.
