摘　　要：开发了一种可用于模拟太空环境,并实现宇航材料释气量精确检测的装置。本文主要介绍了该热真空释气装置的设备组成、装置研制过程中理论计算、热真空释气试验方法以及真空泵组选型设计。针对某宇航材料进行了热真空释气试验并测量了TML(总质量损失)和CVCM(收集到的可凝挥发物)。与已有测试数据对比表明,该材料TML和CVCM误差均满足相关标准中可信度的要求,本试验装置适用于热真空释气试验。A device for simulating space environment and detecting the outgassing of aerospace materials accurately is developed. This paper mainly introduces the equipment composition of the thermal vacuum degassing device, the theoretical calculation in development process, the test method of thermal vacuum degassing and the selection of vacuum pump unit. Thermal vacuum outgassing test for an aerospace material was carried out and the TML(total mass loss) and CVCM(collected volatile matter) were measured. Comparing with the existing data, it is found that the errors of TML and CVCM satisfy the credibility requirements in the relevant standards. This device is suitable for the thermal vacuum outgassing test.
