Abstract EN
The dynamic response of the vibrating screen has a great impact on the screening efficiency and fatigue life of the structures.
For the conventional dynamic design, the consideration of the influence of load weight on dynamic response is lacking.
So, in this paper, taking a very common vibrating screen used in tunnel construction as an example, the relationship between the screen dynamic response and the load weight is studied through numerical simulations.
Firstly, to make sure the accuracy of simulation, the three-dimensional finite element model of a vibration screen is strictly built to maximize consistency with the real screen, and then the simulated results are validated by experiments.
Furthermore, the variation regularity of dynamic response with the load weight and excitation frequency is analyzed based on simulations.
Results show the load weight has obvious influence on the modal shapes as well as the natural frequencies.
There are three regions that will lead to the sudden increase of vibration acceleration: (1) the load weight variates within 0–50 kg and excitation frequency variates within 40–60 Hz; (2) the load weight variates within 10–100 kg and excitation frequency variates within 50–90 Hz; (3) the load weight variates within 80–200 kg and excitation frequency variates within 70–100 Hz.
These results will provide new theoretical reference for the maintenance and further improvement in the dynamic design of the vibrating screen.
