摘　　要：利用有限元分析软件ANSYS对某锂离子电池自动套管专用设备中加热机构的温度分布进行了稳态数值模拟研究,以炉膛温度的均匀性为目标,通过正交试验方法对加热机构中加热管的安装尺寸进行了优化设计,并对最优加热机构进行了试验研究。结果表明,通过有限元分析手段对加热机构进行优化设计是可靠的;加热管的最优安装尺寸为:内侧加热管与胶管的水平距离为40mm,外侧加热管与胶管的水平距离为40mm,外侧加热管与电池底端的垂直距离为-15mm,内侧加热管与电池顶端的垂直距离为10mm。The distributions of the heating mechanism temperature used for lithium ion battery automatic casing machine were researched by steady-state numerical simulation based on the finite element analysis software,ANSYS.A iming at the uniformity of furnace temperature,the installation dimensions of heating tubes of heating mechanism were optimized based on the orthogonal experiment method,and the optimal heating mechanism was researched by experimental method.The results show that the finite element analysis method which was used to optimize the heating mechanism is reliable; and the optimal installation dimensions of heating tubes are：the horizontal distance between inside heating tubes and plastic tube is 40mm,the horizontal distance between outer side heating tubes and plastic tube is 40mm,the vertical distance between outer side heating tubes and the bottom of the battery is-15mm,the vertical distance between inside heating tubes and the top of the battery is 10mm.
