Maglev Platform Bearing Characteristics

Magnetic suspension has many characteristics, such as no rubing, no wearing and tearing, non-lubricating , low consumption , no noise,etc. thus it has a good application prospect in many fields , such as bearing , guide , electronic encapsulation platform ,etc. This paper combines " near zero friction high speed high precise sport 's form and control" subject of" 973 "project of country, study the bearing capacity and stability of a kind of magnetic suspension platform, in order to offer gist which help this magnetic suspension platform's controlled steadily. The main research contents of the paper are as follows:1 Utilized the basic theories of computational electromagnetics, according to the designing requirement on magnetic way of magnetic suspension, designed magnetic suspension platform , analysed and calculated its magnetism way , seted up magnetic suspension platform's magnetic induction intensity and electric magnetic force.2 Used the finite element of ANSYS's analytical software, based on the finite element model of magnetic suspension, analysed 6 degrees of freedom's displacement impacts on magnetic suspension's system stability's law, finded out electromagnetic physics parameter correlated with platform bearing capacity of magnetic suspension's relation.3 Analysed the relative geometry position error of the platform (parallel degree , vertical degree ) to the electric magnetic force and steady influence law of magnetic suspension platform, and gave platform parallel degree , vertical control goal of magnetic suspension.4 Tested magnetic field intensity under the different states of magnetic suspension platform, compared with ANSYS analysis result, verified the exactness of the finite element of ANSYS analysis result.
