【摘要】 基于Simufact Forming构建了V形折弯有限元模型，结合实验验证了模型的可靠性，探究了板厚及模具几何参数对回弹的作用规律。研究发现：板料增厚导致回弹角呈非线性递增，增幅随厚度增大而衰减；下模开口宽度为关键影响因素，上下模圆角半径参数影响较弱。研究成果可为后续角度补偿模型开发提供理论依据。更多还原

【Abstract】 This study established a V-shaped bending finite element model using Simufact Forming,validated the model reliability through experiments,and systematically analyzed the influence of plate thickness and die geometric parameters on springback.The results indicated that increased plate thickness induces a nonlinear growth in springback angle,with the rate of increase gradually decreasing as thickness expands.Among die parameters,the lower die opening width emerged as the most significant factor affecting springback,while the upper and lower die fillet radii exhibited minimal effects.Research conclusions can lay the theoretical groundwork for developing subsequent angle compensation models.更多还原
