| Abstract: | In this paper, impulse excitation method which is simplicity and rapidity itself is used to determine the structural frequency response function of the roll type briquetting machines. By using a fourier analysis system HP5451C, all of the order modal parameters are obtained, 12 order vibration models of the whole machine and 3 main parts (left wall, right wall and bottom case) have been vividly shown. (see video picture). The existing problems of the structure are analysed and some improvements are presented.At last of the paper, several measures to raise the experimental of the method are also discussed. |
