Research abstract
A MULTI-FREQUENCY ELECTROMAGNETIC TEST METHOD IS PROPOSED TO SORT FASELY MARKED STEEL FASTENERS. TESTING WILL CONSIST OF MEASURING THE IMPEDANCE OF A PROBE AT TWO DIFFERENT FREQUENCIES AND TWO DIFFERENT MAGNETIC FIELD STRENGTHS WHEN IN CLOSE PROXIMITY TO THE FASTENER. THE 8 DIMENSIONAL STATE VECTOR GENERATED BY THIS MEASUREMENT WILL BE USED TO SEGREGATE THE STEEL FASTENERS ACCORDING TO GRADE. IT IS ANTICIPATED THAT THE GRADE COULD BE DETERMINED IN AS LITTLE AS A MILLI-SECOND. FIRST PHASE OF THE PROGRAM WILL PROVIDE A DEMONSTRATION OF THE ACCURACY OF ELECTROMAGNETIC SORTING OF DIFFERENT GRADES OF FASTENERS AND PROVIDE A DETAILED SPECIFICATION FOR A PROTOTYPE TEST SYSTEM. IT IS ANTICIPATED THAT BOTH A MANUAL TEST SYSTEM FOR TESTING INSTALLED FASTENERS AND A LARGE VOLUME AUTOMATIC TEST SYSTEM WILL BE SPECIFIED. SECOND PHASE OF THE PROGRAM WILL DEVELOP AND DEMONSTRATE A PROTOTYPE TEST INSTRUMENT AND AN AUTOMATIC PARTS HANDLING SYSTEM.
