【摘要】 在系统设计开发计算过程中,要用到大量的数学计算,由于 Fortran 语言拥有强大的数值计算功能与数学分析能力,因此采用 Fortran 语言编写油膜轴承的计算源程序,但其操作繁复且可视化效果差,鉴于此,使用动态链接库与 VB 进行混合编程,由 VB 设计实现输入、输出的可视化计算应用系统界面。首先提取计算源程序的输入、输出参数,将其编制为可进行动态链接的应用程序,然后在 VB 界面下编程计算,调用 Fortran 动态链接库,并使用 MDI 窗体优化 VB 界面,实现可视化的系统性能计算应用系统。更多还原

【Abstract】 During the calculating process of system design and development,a large amount of mathematical calculation is needed.The source calculation programs of oil-film bearing are developed by Fortran language due to its powerful numeric calculation and mathemat- ical analysis capacity.However,its disadvantage lies in complicated operations and poor visual effect.Due to the above situation,dy- namic link library and VB are used for mix programming.The visual calculation application interface is designed for input and output function by VB.Firstly,input and output parameters are extracted from source programs,and then they are transformed into dynamic link application program.Consequently,calculation results could be visually displayed on VB interface by calling Fortran DLL.Mean- while,VB interface is optimized by using MDI window.Finally,the visual calculation application system could be successfully accom- plished.更多还原
