摘要

在对较大面积座舱盖进行长时间高低温频繁转换的加温疲劳试验时，实现座舱盖外表面温度场的均匀分布是保障试验可靠性的关键所在，也是设计疲劳试验台需要解决的技术难题。本文以座舱盖加温疲劳试验台为研究对象，以相互耦合的航向温差和展向温差定义温度场均匀性，考察不同设计参数对温度场均匀性的影响。选取环形通道的试验段和前过渡段为计算区域，并建立了三维非稳态对流-导热模型，基于计算流体力学（CFD）方法开展座舱盖加温疲劳试验台设计参数的方案优选，详细分析了入口温度控制周期、试验段的特征尺寸、入口流量和前过渡段特征角度对温度场均匀性的影响。研究发现：改变入口温度控制周期不会对座舱盖外表面温度分布产生显著影响，而调整试验段的特征尺寸可以明显改变航向温差和展向温差；此外，增大入口流量可以有效提高座舱盖外表面的温度场均匀性，通过改变前过渡段特征角度可以明显改善由风挡温度引起的温差超标问题，研究结果可为座舱盖加温疲劳试验台的设计方案优选提供理论支持。

Abstract

Uniform distribution of temperature on the outer surface of a large area canopy in heating fatigue tests, in particular for long time and high temperature conversion frequency tests is the key to reliability of the tests, and is also a technical problem for the design of fatigue test-beds. In this paper, we study how parameters of the design of the canopy heating fatigue test-bed influence the uniformity of the temperature field, as defined by the coupled heading temperature difference and spanwise temperature difference. A three-dimensional unsteady convection-conduction model is developed to study the scheme for selection of the design parameters of the test section and the front transition section of the annular channel through Computational Fluid Dynamics (CFD) based simulations. Effects of the factors, such as variation period of inlet temperature, characteristic dimension of the test section, inlet flow rate, and characteristic angle of the front transition section, on temperature field uniformity are discussed. It is found that change of the control period of inlet temperature has little effect on temperature distribution over the outer surface of the canopy, and adjustment of the characteristic dimension of the test section can significantly change the temperature difference in the heading and spanwise directions. In addition, increasing the inlet flow rate can effectively improve the uniformity of temperature field on the outer surface of the canopy. By changing the characteristic angle of the front transition section, the temperature difference caused by the windshield temperature can be significantly improved. The results presented in this study can provide theoretical support for scheme selection for heating fatigue test-bed design of the canopy.
