Abstract

In order to study the problem of beam crack and side plate tearing bring by large-scale and high-speed development of vibrating screen, redundant constraints beam is designed by means of adding redundant constraints to the beam, and vibration experiment system is put up. Input power flow formula of system is derived based on cross-spectral density method proposed by Fahy, the input power flow of improved and original beams is measured, and the input power flow variation with frequency is analyzed. It obtained that, amplitude of input power flow of redundant constraints beam appeared in low frequency, attenuation in high frequency is fast, and at about 100Hz it tends to balance; amplitude of input power flow of original beam appeared in high frequency, attenuation in high frequency is slow, and 150~200Hz it tends to balance. The results showed that, redundant constraints beam has inhibition and attenuation of vibration energy, it beneficial to realize high-speed of vibrating screen.
