摘要：先进高强钢成形后回弹严重影响成形件形状精度,为准确预测并控制回弹,提出一种新的多尺度无网格自适应分析方法,优化工艺参数,降低回弹提高成形精度。利用无网格形函数多尺度特性将应力、应变分解为高、低尺度分量,采用应力、应变高尺度分量表征应力、应变梯度;采取自适应分析技术在高梯度区加密无网格节点;在准确构建先进高强钢本构关系的基础上建立先进高强钢板材成形自适应无网格数值模型。针对先进高强钢U形弯曲进行无网格数值模拟,数值结果表明,所构建的无网格数值模型可准确预测先进高强钢成形后的回弹,有效提高先进高强钢成形质量。

摘要：The objective of this work was the planning, simulation and evaluation of the behavior and interactions of diverse factors in the deep drawing process, in order to prevent defects on formed metal sheet parts. The material used is austenitic stainless steel of 0.4 mm of thickness. Due to the potential high number of experiments, a preliminary selection of cylindrical and hemispherical cup drawing geometries was carried out, as well as a parametric analysis of parts and tools. The influence of the punch and die transition radii, as well as the force of the binder, on the maximum thinning suffered by the material, was studied. The tests were planned by means of CAD/CAE and the design of experiments method. After running the simulation with AutoForm, they were evaluated with FLD, Regression, ANOVA, Six Sigma and Pareto analysis. This sequence allowed us to analyze the influence and sensitivity of several tool and process design parameters and to optimize the process. The results of this investigation have also proven to be useful to simplify and accelerate the design of deep drawing tools.
