摘要
通过对桁架结构的静、动态分析,探讨如何建立桁架的有限元模型及计算方法,并利用MSC.Pat-ran/Nastran程序对该结构进行静、动态分析计算,计算结果与实际情况吻合。
Through a finite element analysis of static and dynamic characteristics for a truss frame,how to create finite element model and calculation method for truss frame is discussed. Then use MSC.Patran/Nastran the truss frame is analyzed and the calculation results are goodly coincident with the experimental results.
