柔性薄膜太阳能电池用精密不锈钢基板冷轧成形的数值模拟
Simulation of Cold Rolling Process of Stainless Steel Strip Used as Flexible Thin Film Solar Cell Substrate
摘要
Abstract
This paper uses the finite element methodl( FEM)to investigate the influence of rolling reduction and tension on stress dis tributed along stainless steel strip for flexible thin film solar cell substrate during cold rolling process. The result shows that proper in crease in rolling reduction can lead to uniform distribution of stress and minimize rolling passes, but the oversize results in uneven plastic deformation. The higher back than front tensile force method can be used to uniformize the distribution of stress along the srip. When the front/back tension is 40 kN/58 kN, the rolled strip facial stress is well-distributed and the peak value turns back to the lowest value. The results indicate that the stress along the stainless steel strip, which is rolled under 30% reduction rate using higher back tension force is ensured to be appropriate and uniform. Afterwards, the stainless steel strip with the thickness0.25 mm is suc cessfully formed under the direction of FEM results. This thickness is accordance with the simulation results and its roughness meets the substrate demands.关键词
