Abstract:
The shuttle-type belt conveyer, as a new type of concrete machine, has been widely used in the pouring hydropower construction and other fields. The finite element model for analyzing the overall structure of shuttle-type belt conveyer was established using ANSYS. The load the shuttle-type belt conveyer suffered under the normal conditions was simulated, and the prestressed modal study and harmonic analysis were performed. The natural frequencies for the first 8-order modals were obtained, and the second modal frequency had the greatest impact on the dynamic performance of shuttle-type belt conveyer. Therefore, the second modal frequency was extracted as an objective function in the multi-objective optimization design, which can lay the foundation for the subsequent optimization design of shuttle -type belt conveyer structure.
