锂电池极片辊压机刚度分析与结构优化
Stiffness Analysis and Structure Optimization of Rolling Mill for Lithium-ion Battery Electrode Manufacturing
摘要
Abstract
In the process of rolling electrodes,due to the contradiction between the energy densityand the material mechanical properties of coatings on the electrode,the roller pressure should be con-trolled strictly according to the compression ratio.Actually,the roller surface made the gap betweentwo rollers difficult to measure through experiments.Consequently,it was difficult to directly quantify the relation between the gap size and roller pressure by using physical prototype.The variations of physical quantities during the electrodes manufacturing process were simplified to build the digitalmodel of rolling mill and electrode deformation.With the help of the digital model,the relation of gapvariation and pressure was quantitatively simulated.According to the above study,on the purpose ofsimulation-driven design,the structural parameters and work condition of digital rolling mill were op-timized by the response surface methodology and multi-obj ective genetic optimization algorithm.The stiffness test has validated the digital model and the simplification hypothesis.These results are im-portant to lay a plan for rolling processes;meanwhile the research and development efficiency is im-proved by the response surface-based design optimization.关键词
