【摘要】 利用Marc软件对不锈钢波纹板的冷弯成形过程进行了三维弹塑性有限元模拟,建立了冷弯成形的有限元模型,得到了不同成形阶段金属板材的等效应力、横向应变及纵向应变变化和分布规律,模拟结果表明:变形是由横向弯曲变形与纵向弹性拉伸变形联合作用的结果,且横向弯曲变形要比纵向弯曲大的多。更多还原

【Abstract】 Using the Marc software Carries on the three dimensional elastoplasticity finite element simulation to cold bending forming process of the stainless steel corrugated plate,establishes finite element model of the corrugated plate,obtaines the analysis different forming stage metal plate equivalent stress,the lateral strain,the longitudinal strain change and the distribution rule,The results showes that:the deformation is by the transverse curl distortion and the longitudinal elasticity stretch elongation joint action result,and the transverse curl distortion than a large number of the longitudinal bending.更多还原
