应用SolidWorks的焊件功能实现对空间环境模拟器热沉的快速建模

热沉是空间环境模拟设备的重要组成部分，其主要功能是实现冷黑环境模拟。由于热沉的独特结构，传统的从零件到装配体的热沉三维建模过程繁琐且效率低下。文章介绍应用SolidWorks三维设计软件的焊件功能实现对热沉的快速建模方法。通过某环模设备热沉的建模过程，详细描述了这种快速建模方法的步骤及要点。

Fast modeling of thermal shroud of space simulator with SolidWorks welding function

The thermal shroud is an important part of the space simulator.It provides the cold and dark conditions just like in the space environment.The traditional ＂components to assembly＂ modeling method is complex and is not very convenient to implemented,because of the special structure of the thermal shroud.The paper proposes a new fast modeling method of the thermal shroud with SolidWorks’s welding function.The modeling process of a thermal shroud for the space simulator is illustrated step by step.This method is shown to be efficient.
