Non-contact magnetic exciter for complex modal testing of rotating machinery

摘要

An object of the present invention is to provide a non-contact electromagnet excitation apparatus which is capable of applying excitation to a desired position of a rotating body in a rotating device complex mode test of a rotating machine and which is easy to install, disassemble and move.;According to the present invention, in the excitation device for measuring the excitation response of the rotating body 10 after applying the excitation force positioned on the circumference of the rotating body 10, so as to surround the circumference of the rotating body 10 Positioned support means 111 and the plurality of excitation means 120 is installed in the support means 111 is movable in the direction of the center of rotation of the rotating body 10 and applying an excitation force to the rotating body 10 And, a plurality of excitation force measuring means 140 for measuring the excitation force generated by the excitation means 120, and a plurality of excitation response measuring means for measuring the excitation response to the rotating body 10 by the excitation force ( 130, and an excitation device including an analyzer 150 for receiving and analyzing the signal output from the excitation force measuring means 140 and the excitation response measuring means 130.
