摘要
针对回转体和扁平体结构的大尺寸C/SiC复合材料构件,设计了可表征缺陷检测分辨率的像质计,研究了射线能量、准直器宽度等因素对不同类型构件检测结果的影响情况。结果表明:射线能最、准直器宽度及构件尺寸、形状等因素决定了构件内部缺陷检测分辨率;准直器的选择取决于构件的尺寸、形状等特征;射线能量的选择取决于构件的最大穿透厚度。
Based on the large scale revolved body and flat body made of the C/SiC composite material, a CT image indicator for the C/SiC composite CT results' evaluation was designed and tested, the effect of the X ray energy, the opening of the collimator and other parameters were studied. The result concluded that the CT resolution are determined by the X ray energy, the opening of the collimator, the dimensions and the shape of the samples;the collimator opening are related to the samples' dimensions and the shape;the X ray energy are detennined by the max penetration path of the sample.
