通过钻孔法测试了T型整体化复合材料结构件在不同固化工艺方案下的残余应力,并研究了多墙类加筋壁板的腹板和蒙皮的残余应力分布,以及不同钻孔深度对结构件内部残余应力测试结果的影响。研究结果表明:共固化方式下产生的残余应力要小于胶结共固化方式下的残余应力。 The residual stress of T-shaped monolithic composite structures under different curing schemes was tested by drilling method. The residual stress distribution of webs and skins with multi-wall stiffened panels was studied, Impact on Residual Stress Test Results in Structural Parts. The results show that the residual stress produced by the co-curing method is smaller than the residual stress under the co-curing method.

主成分分析(PCA)法在掌纹识别方面可以取得较好的效果。但是随着掌纹图像库的扩大,PCA转换矩阵训练时间迅速增长;注册新掌纹时,需要重新训练PCA转换矩阵,添加注册掌纹的代价随着掌纹库的增大迅速增加。如何能够在保持PCA识别效果的情况下提高使用的便捷性成为PCA广泛应用的主要障碍。提出了一种以PCA重建误差为分类依据的PCA重建误差掌纹识别方法。该方法与PCA法基于相同的原理,在采用最近邻分类器时
