物性参数对陶瓷制品红外无损检测影响的研究

Study of Influences for Thermophysical Parameter of Ceramic Product on Nondestructive Testing

本文应用陶瓷坯体红外无损检测的数学模型及有限元方程，采用高斯直接法，利用计算机模拟了陶瓷材料物性参数对红外热成像无损检测的影响，找出了红外无损检测的一些基本规律和影响因素。结果表明：制品的导热系数与缺陷的导热系数是决定红外无损检测精度和灵敏度的主要因素。

Using the mathematical model and finite equation of ceramic body,this paper simulates the influences of thermophysical parameter of ceramic product on nondestructive testing and shows the thermal conductivity of ceramic product and the defect is the major factor influenced on the sensitivity and the accuracy of nondestructive testing.
