MatLab与Fortran混合编程实现结构优化和可靠性分析

Realization of Structural Optimization and Reliability Analysisby Mixing Programming of MatLab and Fortran

为有效利用MatLab和现有Fortran有限元程序,采用MatLab与Fortran混合编程。通过MatLab程序接口,将MatLab与Fortran有限元程序成功连接实现平面桁架结构的静力分析;然后在MatLab环境下运用优化工具箱和统计工具箱编程实现了平面桁架的结构优化设计和可靠指标的计算。

The mixing programming of MatLab and Fortran is used for the effective use of MatLab and existing Fortran finite element programs.Through the MatLab programming interface,the MatLab and Fortran finite element programs are successfully connected to implement the static analysis of plane truss structures.Then the optimal toolbox and statistics toolbox of MatLab are used for programming to realize the structural optimization and reliability analysis of plane truss structures.
