Theoretic analysis of forming and springback for sheet metal air bending
板料自由弯曲成形及回弹理论解析
Based on the assumption of rigid and linear work-hardening, and the analogy between the deformation of the rigid and linear work-hardening beam after yield and the linear elastic beam, computing model and formula for air bending of sheet-metal V-shape are set up, program to calculate air bending force is realized and basic features of air bending are analyzed.
基于材料刚-线性强化的假定,以刚-线性强化梁在屈服以后的弯曲行为与弹性梁的弯曲行为相类似为前提,建立了板料V形自由弯曲过程的计算模型和数学方程,实现了自由弯曲力的程序求解,并分析了自由弯曲的基本特征。
It is found that the curves can basically reflect changes in the layout of natural developing bends.
