研究设计了一种新型的曲耙结构,并借助多物理场协同仿真平台ANSYS Workbench,基于单向流固耦合理论分别对直耙和曲耙在实际工况下和泥浆的耦合系统进行了仿真计算。结果表明,在相同的进料浓度的情况下,曲耙较直耙能够更快地达到稳定运行状态,并且能够沉降出更高浓度的底流泥浆;稳定运行时曲耙的最大等效应力及最大变形量比直耙大,但均满足强度要求,不影响整机的稳定运行。
A new curved rake structure was designed and studied. Based on the multi-physics co-simulation platform ANSYS Workbench, the coupling between the straight rake and the curved rake under actual conditions and the mud coupling system were simulated respectively based on the unidirectional fluid-solid coupling theory . The results show that, at the same feed concentration, the harrow can reach steady state more quickly than the direct harrow and can sink a higher concentration of underflow slurry. The maximum equivalent stress and the maximum of the harrow in stable operation Deformation than the straight rake, but all meet the strength requirements, does not affect the stable operation of the machine.
