本文根据C型多点成形压机机架结构、受力状况,以三维实体为单元,建立了压力机机身有限元模型和机身结构优化的数学模型。有限元分析表明,本模型行之有效,优化结果理想。
According to the structure and force of C-shaped multi-point forming press, the finite element model of the fuselage of the press and the mathematical model of the fuselage structure optimization are established based on the three-dimensional entity. Finite element analysis shows that this model is effective and the optimization result is satisfactory.
