Abstract:
It not only can increase the mixing quality of aggregate, but also can promote the productivity of mixing plant to study the dynamic performance of vibrating screen in asphalt mixer. With the finite element software of ANSYS, this paper built the finite element model of vibrating screen box in asphalt mixer, analyzed its modal characteristics, harmonic responses and the distributed regularities of dynamic stress, and studied the intensity and stiffness of vibrating screen. With the intensity test of the vibrating screen, the dynamic stress of vibrating screen was gotten to verify the ANSYS analysis results. The testing results show that this model can accurately reflect the actual structure features of vibrating screen box; its natural frequency is not coincided to working frequency, so there is not resonance during the normal operation of the vibrating screen; the dynamic rigidity and strength of vibrating screen can meet the design requirement. 2 tabs, 8 figs, 10 refs.
