利用ANSYS有限元软件,对相同的浇钢过程中2种不同结构的金属底座进行热/力的间接耦合模拟。研究表明,1#底座对角方向最大等效应力值达601 MPa,是产生裂纹的主要因素,裂纹易产生于底座的下表面,且在底座的下表面沿底座中心45°方向上存在一明显的应力集中区域;2#金属底座的最大等效应力值降低为397 MPa,能够有效避免裂纹的产生,结构较合理。 ANSYS finite element software was used to simulate the thermo-mechanical coupling of two kinds of metal base with different structures in the same steel pouring process. The results show that the maximum equivalent stress in the diagonal direction of # 1 base reaches 601 MPa, which is the main factor of crack initiation. Cracks easily occur on the lower surface of the base, and there is an obvious Of the stress concentration area; 2 # metal base maximum equivalent stress reduced to 397 MPa, can effectively prevent the generation of cracks, the structure is more reasonable.
