spatial grid structure meaning in Chinese

空间纲架结构

Based on the modal analysis data of the displacement of the spatial grid structure getting by the structural finite element analysis software ansys , the modal analysis technology of the axial member straining rate is used to identify the damage of the spatial grid steel structure in different damaged conditions and is found to be able to accurately position the damaged places of the spatial grid member
文中通过结构有限元分析软件ansys得到网架结构位移模态分析数据，采用杆件轴向应变变化率的模态分析技术针对不同损伤状况的钢结构网架进行损伤识别，能够较为准确地诊断出网架杆件的损伤位置。
