文章针对航天器组件试验过程中温度场不均匀和单一控温点难以全面控制组件温度的问题,研究了试验箱内温度场的均匀性分布,组件不同部位在箱内的温度分布规律以及影响这种分布的因素。通过温度测控试验方法的研究,配合所研制的多路温度测控系统,确定了组件试验过程中温度控制点的选取方法,解决了热试验中组件局部温度失控问题,提高了组件的试验安全性和试验质量。
In this paper, aiming at the problem that the temperature of the module is difficult to be controlled completely due to the uneven temperature field and the single temperature control point during the test of the spacecraft module, the uniformity of the temperature field in the chamber, the temperature distribution in different parts of the module, The distribution of factors. Through the research of temperature measurement and control test method, with the multi-channel temperature measurement and control system developed, the method of temperature control point selection in the process of component test was determined, which solved the problem of local temperature runaway in the thermal test and improved the test safety of the module. Test quality.
