LWS400卧螺离心机参数变化对转鼓强度和刚度的影响

Influence of Parameters Changing of LWS400 Horizontal Spiral Centrifuge on the Strength and Stiffness of the Rotating Drum

采用Solid Works软件建立LWS400卧螺离心机转鼓几何模型并导入ANSYS Workbench软件中进行有限元分析。分别改变转鼓转速、转鼓壁厚和液池深度三个参数并讨论由此对转鼓强度和刚度的影响,以便为后续的优化设计方案提供参考。讨论结果表明:转鼓转速的提高或壁厚的减小都对转鼓强度和刚度有明显的影响,液池深度的变化对转鼓强度和刚度的影响不大。

The geometric model for the drum of LWS400 Horizontal spiral centrifuge was established by using Solid Works software, and finite element analysis of the geometric model was carried out by ANSYS Workbench software. Effect of changing speed, wall thickness and liquid pool depth on the strength and stiffness of the drum was investigated, which could provide a reference for subsequent optimizing plans. The results show that the increase of rotational speed or the decrease of wall thickness has obvious effect on strength and stiffness of the drum. The change of liquid pool depth has little effect on strength and stiffness of the drum.
