| Abstract: |
| The experience-based design of large flotation cell tanks led to excessive redundant structure and large safety factor, resulting in the large weight. Therefore, reducing weight and reducing manufacturing costs had become an urgent need solved problem for flotation cell R D and manufacturing enterprises. In this paper, first using the numerical calculation method, a three-dimensional finite element model of the original tank was established, its strength and stiffness was analyzed, and the redundant parts were found. Then, a lightweight design scheme was developed, and the structural strength and stiffness of the lightweight tank were analyzed again. On the premise of meeting the design requirements, the dynamic characteristics were analyzed to obtain the various stages natural frequencies and the corresponding modalities of the lightweight tank. The minimum natural frequencies was greater than the frequency of the running parts of the flotation cell, and the resonance did not occur. Finally, the performance of the lightweight tank was evaluated. On the basis of satisfying the static and dynamic characteristics, the weight was reduced by 15.25%, and the effect was very obvious. |
