| Abstract: | Tries to employ the experimental modal analysis method to study the load effect of the flapping and jumping surface loading on the frame or beam in a vibration screen and obtains the equivalent dynamic load expression.lt is found that this type of load is an action composed of a series of impulse force with the presence of the f/2 order harmonic excitation, where f means the working frequency of screen, and also the superharmonic resonances. The result is available to the dynamic strength design of the frames in screen machine. |
