The invention relates to a test device for simulating a space environment, and the device comprises a reaction chamber which is connected to a vacuum chamber and is located in the vacuum chamber, and the interior of the reaction chamber and the interior of the vacuum chamber are in a vacuum environment; the input and output assembly is used for inputting and outputting a medium into the reaction chamber; the detection assembly is used for detecting environmental parameter values in the reaction chamber and the vacuum chamber; the adjusting assembly is used for adjusting medium quantity input and output to the reaction chamber by the input and output assembly; the controller sends an adjusting instruction to the adjusting assembly based on a detection value of the detection assembly, the adjusting assembly adjusts the input and output assembly so that multiple environmental parameter values in the reaction chamber can be within a preset value range, and the multiple environmental parameters at least comprise the temperature, the vacuum degree, the pressure and the electric field. According to the test device, the internal pressure and the external pressure of the reaction chamber can be relatively balanced, so that the influence of the sealing effect of the test device on the test at an ultralow temperature is reduced, and more accurate test data is obtained.
本申请涉及一种模拟空间环境的试验装置,包括反应腔室连接于真空腔室并位于真空腔室内部,反应腔室内部与真空腔室内部均处于真空环境;输入输出组件用于对反应腔室内部输入输出介质;检测组件用于检测反应腔室与真空腔室内的环境参数值;调节组件用于调节输入输出组件向反应腔室输入输出的介质量;控制器基于检测组件的检测值发送调节指令给调节组件,调节组件调节输入输出组件,以使得反应腔室内的多个环境参数值在预设值范围,多个环境参数至少包括温度、真空度、压力、电场。该试验装置能够使得反应腔室的内外压力相对平衡,从而降低超低温时因试验装置的密封效果对试验的影响,进而得到更准确的试验数据。
