针对某星载设备信息箱中插槽式固定电路板在力学试验中出现引脚断裂这一问题,在对电路板上的元器件简化为等质量立方体的基础上,用Solidworks软件对信息箱机械结构建立了精确的几何模型,用MSC/Nastran软件进行了模态分析。

According to the characteristics of substrate draw-foot image,a BP neural network has been found to recognize them,and a software package based on those have been developed and implemented.

根据基板引脚图像的特征,建立了基于人工神经网络中BP算法的网络模型,并利用VC++6。
