Abstract

Abstract: In this study, experimental and theoretical results carried out on a cantilever hollow operating shaft, in order to determine the natural frequency of hollow operating shaft and in experimentally aims to provide a non-contact electromagnetic impulse. In this experimental work, to creating impulse on a hollow operating shaft electromagnet was use. To analyze time domain signal of static hollow shaft with an impulse effect, in order to measure natural frequency of hollow shaft. To analyze time domain signal of a hollow operating shaft without an impulse effect, in order to measure natural frequency of hollow shaft. To analyze time domain signal of a hollow operating shaft with an impulse effect, in order to measure the natural frequency of a hollow operating shaft. The time domain converted into frequency domain by using fast Fourier transform (FFT). Frequency measurement of hollow operating shaft could be one such parameter and in general it is difficult to determine natural frequency of hollow operating shaft. In this project an effort is made to determine the natural frequency of hollow operating shaft by non-contact impulse method, a new approach is made use of. And the results obtained by experimental and theoretical methods correlated well.
