热特性模拟广泛应用于电力、消防、工业、医疗、安防等国民经济及军事部门,而验证是模拟软件优化发展过程中重要的一个环节;对于热特性模拟软件来说,一般通过实验验证对软件进行验证。为了有效快速地进行验证,将地面物体简单处理为CUBI及立方体模型。放置于各实验模型物体表面特征位置(面中心、中线)的热电偶可获得物体的实测温度数据,模拟软件所需的某些输入参数可以通过风速仪等相关仪器获得。通过对实验及计算数据的比较验证了该模拟软件的精确度基本符合要求,并且还发现了在模拟软件中应该注意的一些问题。
熱特性模擬廣汎應用于電力、消防、工業、醫療、安防等國民經濟及軍事部門,而驗證是模擬軟件優化髮展過程中重要的一箇環節;對于熱特性模擬軟件來說,一般通過實驗驗證對軟件進行驗證。為瞭有效快速地進行驗證,將地麵物體簡單處理為CUBI及立方體模型。放置于各實驗模型物體錶麵特徵位置(麵中心、中線)的熱電偶可穫得物體的實測溫度數據,模擬軟件所需的某些輸入參數可以通過風速儀等相關儀器穫得。通過對實驗及計算數據的比較驗證瞭該模擬軟件的精確度基本符閤要求,併且還髮現瞭在模擬軟件中應該註意的一些問題。

Thermal characteristics modeling is widely used in national economic and military departments, such as electric power, fire control, industry, medical treatment and security;and validation is an important step in the development and optimization of modeling software. For thermal characteristics modeling software, experimental validation is usually utilized to verify. In order to test rapidly and effectively, we simply take the geometry of ground vehicles as CUBI or cube. The thermocouples installed in feature positions of the surface of experimental model (surface center, the center line) to obtain measured temperature data of the object;some input parameters the modeling software requires can be gained via the anemometer and related instruments. Through the comparison of the experiment and calculation data, the accuracy of the modeling software is proved to basically conform to requirements;and some problems of the modeling software which should be paid attention to are also found.
