Electromechanical Coupled Chaotic Vibration Study Of Electromechanical Integrated Toroidal Drive

Electromechanical integrated toroidal drive is an electromechanical coupled drive,Drive integrates drive, electromagnet and control and has the characteristics such asstructure compact, no touch, no abrasion and dispense with lubrication and so on. Onaccount of nonlinear coupled force, the system probably appears complicated nonlineardrive. Therefore, study of electromechanical coupled chaotic vibration ofelectromechanical integrated toroidal is great theoretical and practical significance. Mainresults of paper are as below:The electromechanical coupled dynamic model of electromechanical integratedtoroidal drive is founded, and considering nonlinear electromagnet coupled force,nonlinear dynamic differential equations are educed. The time domain response isseparately achieved by L-P method and Runge-Kutta method.The range of the theoryanalysis is determined by comparing the numerical and the analytical solutions.When no considering worm vibration, nonlinear dynamic differential simplifiedequations of electromechanical integrated toroidal drive are educed. The equations aresolved by Runge-Kutta method. The bifurcation rules of electromechanical integratedtoroidal drive are obtained. According to bifurcation maps, power maps, Time domainwaveform, Phase maps and Poincare maps, the system’s bifurcation evolution rules areobtained with parameters changing, when planetary cone half angle is 0°and 10°.When considering worm vibration, nonlinear dynamic differential equations ofelectromechanical integrated toroidal drive are solved by Runge-Kutta method. Accordingto bifurcation maps, power maps, Time domain waveform, Phase maps and Poincare maps,the system’s bifurcation evolution rules are obtained with the parameters changing,whenstructural parameters are deifferent.Nonlinear dynamic voltage equations of power system are educed.Using Timedomain waveform, Plane phase diagram, Three-dimensional phase diagram and frequencyspectrum analys mechical and electrical parameters on the effect of nonlinear system.Using mixed programming method of MATLAB and VB，a friendly interface, simple operation of the simulation software is developed, according to matlab own COMcomponent technology. Efficiency of study on chaotic vibration is improved.
