摘　　要：以模块化建模的思想，将氦制冷系统划分为网络部分和换热部分。针对各设备在系统中的网络特性分别建立其数学模型及系统仿真模型，并利用仿真软件对整个系统进行仿真计算，对氦制冷系统的静、动态特性进行分析，得出对设计和调试有用的结论。According to the modular modeling concept, the KM6 Helium refrigerationsystem is divided into the network part and the heat-transfer part. The mathematics model andthe simulation model of equipment are established respectively based on their network characteris-ties. Then by a simulation soft, the whole system simulation model is established and calculated.After analyzing the static and dynamic characteristics of the system, some conclusions useful tothe design and debugging of the system are given.
