摘要
采用不完全等效刚度和不完全等效质量法,应用MSCPatran和MSCNastran软件对某大型工程细长薄壁结构振动进行有限元计算,并分析计算结果,为工程设计提供参考.
Using the stiffness and mass with imcomplete equivalent, the vibration of some large engineering structure with spindly and thin shell is analysed by adopting the MSC Patran and MSC Nastran. Some references are provided to the engineer design bv comnarine the results.
