摘要:

注塑模具冷却管网计算,可以准确预测冷却液的压力和和管网的流量.目前存在两种基本的计算方法都有缺陷:回路法计算烦琐,迭代速度慢;而传统的节点法当管道流量为零时液导矩阵奇异.根据管网基本方程式,建立了新的数学模型,提出了一种改进的节点法.给出了计算程序框图,并编写了电算程序,新方法有效地克服了传统方法的弊端,经实例计算表明,可以快捷准确地进行注塑模具冷却管网的分析计算.

Abstract:

Injection mold cooling pipe network calculation can accurately predict the coolant pressure and flow rate of the pipe network. At present, there are two basic calculation methods with shortcomings: the loop method is cumbersome and the iteration speed is slow; However, the traditional nodal method has a singular liquid conduction matrix when the pipeline flow rate is zero. According to the basic equation of pipe network, a new mathematical model is established and an improved node method is proposed. The calculation program block diagram is given, and the computer calculation program is written, the new method effectively overcomes the shortcomings of the traditional method, and the case calculation shows that the analysis and calculation of the injection mold cooling pipe network can be carried out quickly and accurately.
