摘要
采用三维造型软件SolidWorks建立了某型号径-轴向辗环机轴向轧制机构的实体模型。以有限元软件ANSYS为分析平台,通过合理处理接触、约束和载荷等边界条件,建立了有限元分析模型,对轴向轧制机构进行了三维弹性接触分析,得到了轴向轧制机构及主要部件的等效应力、位移变形、等效应变。对变形角进行了定义,提出了求解变形角的方法。计算结果表明,变形角为0.041°时,各部件的最大等效应力均小于屈服极限,轴向轧制机构刚度符合设计要求,各部件满足强度要求。
Using SolidWorks,axial rolling assembly model of ring roiling mill was built. Using ANSYS,finite element a nalysis model was established through processing contact and constraints and loads, then three dimensional elastic contact was analyzed to the axial rolling assembly and the equivalent stress, strain and deformation displacement of axial rolling assembly and its parts were got. Deformation angle was defined and the method how to solve the deformation angle was put forward. The result shows that deformation angle is only 0. 041° and the maximum stress of various components is less ihan the yield limit,so the rigidity of the ring rolling mill meets the design requirement and its parts meet strength requirement.
