CT models come from the three-dimensional data of industrial CT test which contain the internal defects, and can draw the more accurate conclusion rather than some ideal models. A CT finite element geometry model of three different ceramic components, containing internal details such as inner defects, was proposed based on the CT non-destructive test. The stress distributions of ceramic components were analyzed by both an ideal finite element model and a CT finite element model. It is indicated that the STL files obtained from the industrial CT test data can be processed to obtain the geometric model to realize the finite element analysis. The results of stress distribution obtained by the fault-free CT model are similar to those obtained by the ideal model. However, the simulation data obtained by the CT model are closer to the results under the actual working conditions when there are defects or special structures.

通过工业CT的三维数据形成有限元分析的几何模型包含内部缺陷等细节信息,与理想模型相比更有利于获得准确的模拟结果。以陶瓷部件CT无损检测的三维数据为基础,建立对应的有限元几何模型,研究了理想模型与CT模型在不同工况下的应力分布差异。结果表明:工业CT数据经过处理能够建立有限元几何模型;无缺陷的CT模型与理想模型得到的应力分布结果相当,但是存在缺陷或特殊结构时,CT模型获得的模拟结果更接近实际工况。

通过工业CT的三维数据形成有限元分析的几何模型包含内部缺陷等细节信息,与理想模型相比更有利于获得准确的模拟结果。以陶瓷部件CT无损检测的三维数据为基础,建立对应的有限元几何模型,研究了理想模型与CT模型在不同工况下的应力分布差异。结果表明:工业CT数据经过处理能够建立有限元几何模型;无缺陷的CT模型与理想模型得到的应力分布结果相当,但是存在缺陷或特殊结构时,CT模型获得的模拟结果更接近实际工况。

CT models come from the three-dimensional data of industrial CT test which contain the internal defects, and can draw the more accurate conclusion rather than some ideal models. A CT finite element geometry model of three different ceramic components, containing internal details such as inner defects, was proposed based on the CT non-destructive test. The stress distributions of ceramic components were analyzed by both an ideal finite element model and a CT finite element model. It is indicated that the STL files obtained from the industrial CT test data can be processed to obtain the geometric model to realize the finite element analysis. The results of stress distribution obtained by the fault-free CT model are similar to those obtained by the ideal model. However, the simulation data obtained by the CT model are closer to the results under the actual working conditions when there are defects or special structures.
