The Research Of Material Magnetic-parameter Metering Equipment

In view of the research situation and trend of development of material magneticparameter metering equipment, elaborated material the basic definition of magneticparameter, has been clear about the important meaning of determination materialmagnetic parameter, discussed the research situations as well as advantages anddisadvantages of domestic and foreign in this kind of equipment, had determined thenecessity of study this kind equipment.According to the electromagnetism related basic theory and recombination domesticand foreign quite advanced practice of this kind equipment survey spot. enhances strongpoints and avoids weaknesses, in situations of stipulated the determination gap ofdetermination spot is10-40mm, can produce the biggest magnetic field strength is8000Oe, has identified magnetic potential of solenoid coil, the thickness and height of the coiland the coil wire diameter, the number of turns of coil and current. Through consultingthe large number of data, determine the measurement part of the pole shape, then the useof ANSYA software, through the definition material properties, set parameters, builds thegeometric model, Carries on the mesh creator, exert the current density to the coil unit,computate cell model，at the same time simulation model pole and traditional pole’smagnetic lines, through the distribution map of contrast magnetic line of force, haddetermined use new magnetic pole than traditional magnetic pole head, its result is moreaccurate.GPIB bus is a kind of parallel external bus, widely used in automatic test system。Analysis and research GPIB and USB agreement, draws up the GPIB-USB connectionconnection diagram, this chart to completing the connection analog to digital conversionhas the guiding sense, its goal is transforms the GPIB connection into the conveniencequick USB connection, causes collected data quick transmission in computer. Establishesthe data analysis procedure with Vb, its function is that automated analysis computationthe data collected and put data out.The research of the device, can rapidly and accurately measuring the magneticparameters, and greatly reduces the testing time and cost of production, to processing,construction, metallurgy and other industries have important practical significance.
