Abstract

This article presents the results of a numerical experimental study on the simulation of the dry ice compaction process. The first part of the article presents a description of the material used, material models and the methodology of experimental research. In the second part, numerical and experimental study results are presented. For the purpose of comparison, a parametric method based on the residual sum of squares was used. The application of the indicated method fills the gap in the available literature as the authors are not aware of any existing data from previous studies on the method of comparing the results of numerical tests in terms of the obtained results and the change of the value of the tested parameter as a function of another variable. The results of this study can be useful in research work aimed at further development of the process of extrusion and compaction of dry ice using Drucker-Prager/Cap and modified Cam-Clay material models for instance for optimization of geometric parameters of parts and components of the main assembly of the machine used in the process of dry ice extrusion.

摘要

本文介绍了干冰压实过程模拟的数值实验研究结果。文章的第一部分介绍了所用材料、材料模型和实验研究方法。第二部分给出了数值和实验研究结果。为了进行比较，使用了基于残差平方和的参数方法。该方法的应用填补了现有文献中的空白，因为作者未发现以往研究中有关于根据所得结果以及测试参数值随另一个变量的变化来比较数值测试结果的方法的任何现有数据。本研究结果可用于旨在进一步开发干冰挤压和压实过程的研究工作，例如使用Drucker-Prager/Cap和修正剑桥黏土材料模型来优化干冰挤压过程中所用机器主要组件的零件和部件的几何参数。
