摘要
复杂的煤矿井下,掘进机回转台需要承担因煤岩介质变化而受到交变载荷激励,其受力变化较大,应力和应变情况比较复杂。因此,对其回转台进行有限元分析是十分必要的。通过应用UG软件建立EBZ260掘进机回转台的三维模型,进行了静态力学分析、模态分析、瞬态动力学分析及耐久性分析。为其优化结构设计和提高性能与可靠性提供了理论依据。
Coal mine complex, Roadheader swivel table to bear due to changes in coal and rock media been alternating load, its force larger changes, stress and strain the situation is more complicated. Therefore, the finite element analysis of its swivel table is essential. In this paper, through the application of established software EBZ260 UG Roadheader swivel table dimensional model for the static mechanical analysis, modal analysis, transient dynamic analysis, durability analysis. Optimization of structural design and improve its performance provides a theoretical basis.
