摘要：为了对辐射热防护测试仪的设计进行优化，分析其设计原理，通过计算机数值模拟的方法，探讨灯管长度、数量、直径、间距4个设计要素对辐射热防护测试仪关键性能指标的影响；采用单因素分析方法得出辐射热防护测试仪的性能提升，可以通过调整灯管数量和灯管间隔来实现，而灯管直径和长度不是需要特别关注的要素；指出：灯管数量为8支、间距为15 mm是较优的选择；其综合效果需进一步通过两个因素的组合进行比较分析。

Abstract:In order to optimize the design of the radiation heat protection tester,analysis  is done to the design principle.Through the computer numerical simulation method,probing is done to the effect of tube length,number,diameter and the spacing on the radiation heat protection tester regarding the key performance.The single factor analysis proves that to upgrade the performance of radiant heat protection tester,it is necessary to do adjustment on the number of tube and tube spacing while the tube diameter and length are not so important.Conclusion is made that the best choice is to use  8 lamps with spacing of 15 mm.The combined effects of the two need further comprehensive analysis.
