MSC Patran/Nastran软件在7.5m天线结构的应用

Structure Analysis of 7.5 m Antenna in MSC PATRAN/NASTRAN

采用MSC Patran和MSC Nastran软件对某大型天线进行了结构强度有限元分析。阐述了天线结构进行力学分析的必要性,并给出了应用MSC Patran和MSC Nastran软件对天线结构分析的一般步骤。最后得出了天线在不同姿态时的变形及应力数据,并经过实际电气指标的测试来进行验证,满足实际指标的使用要求,验证了MSC软件对天线结构分析结果的正确性。

Fine mesh finite element analysis on structure strength of a certain antenna is performed by using MSC Patran and MSC Nastran. The necessity of antenna structure analysis is expounded. The basic procedure of antenna structure analysis in MSC Patran and MSC Nastran software is given. Finally, the main data of deformation and stresses of reflector antenna at different positions are obtained. By comparing with the experimental data, it is shown that the result of analysis is correct.
