摘要
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。
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.
