基于MARC的锂离子电池套胶管机构的优化设计

Optimal Design of the Lithium-ion Battery Casing Mechanism Based on MARC

为提高电池套胶管工艺的送料精度,对18650型锂离子电池套胶管机构进行了设计和分析;利用有限元分析软件MSC.MARC对胶管在中心导柱作用下的涨形过程进行了建模和数值模拟,探讨了套胶管机构的结构参数对送料时热缩胶管受到的阻力的影响规律,并根据模拟结果获得了最优的结构参数。结果表明:当套胶管机构的中心导柱鱼尾宽度为23 mm、鱼尾角度为14°时,胶管受到的送料阻力最小,能有效减少胶管在胶管送料过程中的打滑现象。

In order to improve the feeding accuracy of the casing process of battery, the 18650 cylinder lithium-ion battery casing mechanism were designed and analyzed. The spreading process under the center shaft of the hose was simulated by the finite element software MSC. MARC, and the effect of structure parameters of casing mechanism on the drag force on the heat shrinkable hose during feeding was discussed, and the optimal structure parameters were obtained based on the simulation results. The results show that when the end width of the center shaft in casing mechanism is 23 mm, and the end angle is 14°, the feeding resistance is the minimum, which can reduce the sliding of the hose effectively during casing.
