基于板料成形模拟的专用软件Autoform,以武钢材料真实数据库进行材料定义,建立了抗凹性数值分析模型,分析了不同材料的抗凹性,总结了材料厚度和屈服强度等指标对于材料抗凹性的影响。研究表明,用有限元模拟方式研究汽车用钢抗凹性具有较高的准确度和可靠性;选择屈服强度较高、厚度较大的材料可提高覆盖件的抗凹性能,但同时需兼顾材料的冲压成形性能,以达到最佳效果。
Based on the special software of sheet metal forming simulation Autoform, the material is defined by the real database of WISCO, the numerical analysis model of anti-concave is established, the anti-concave property of different materials is analyzed, and the material thickness and yield strength are summarized. Sexual effects. The research shows that the finite element simulation method is used to study the anti-concave property of automobile steel with high accuracy and reliability. Choosing materials with higher yield strength and larger thickness can improve the anti-concave performance of the cover, Stamping performance, in order to achieve the best results.
