基于ANSYS保温包装球壳模型的建立

Spherical Shell Models for Insulating Packages Based on ANSYS

将实际保温箱尝试用不同球壳模型表达,实现了三维热传递模型向一维模型的转换,借助ANSYS热分析,进行数值模拟,分析了转换模型的保温时间及其与实际保温箱的相对误差。结果表明,当箱体一个内表面接近正方形,内尺寸最大值与最小值的比值小于2时,采用与实际保温箱内体积相等、厚度相等转化而来的球壳模型,最能真实反映实际保温箱的传热过程,这为保温包装优化设计、降低包装成本提供了依据。

In order to realize the three-dimensional heat transfer calculating to one-dimensional,several different spherical shell models were developed.Numerical simulation was carried out based on ANSYS heat transfer analysis to analyze the heat preservation time of the model and the relative error between the model and practical insulating package.The results showed that spherical shell models can furthest reflect the heat transfer process of real insulating package when inside surface of package is close to square and the ratio of maximal size to minimal size of package is less than 2,in which the volume and the thickness of spherical shell model equals to that of the insulating package.The purpose of this research was to provide reference for optimal design of insulating package and to reduce packaging cost.
