基于COM组件的MATLAB和VB混编方法在机械可靠性工程中的应用

摘要

The MATLAB program is powerful at scientific computation, while the Visual Basic ( abbr. VB) program is convenient and realizable at developing friendly user interfaces. In order to fully exert both strengths, the paper presents a new, simple and practical program interface technology that utilizes COM components to create DLL files to realize the linkage between MATLAB and VB. Then Monte Carlo simulation is carried out with cylindrical spring deformation values to fully reflect the superiority of MATLAB and VB mixed programming. Computations have validated the idealness of computational performances.%MATLAB程序具有强大的科学计算能力,而Visual Basic程序(以下简称VB)在开发友好用户界面的方面简单方便,易于实现.为充分发挥二者优势,介绍一种新型、简便、实用的程序接口技术,利用COM组件生成DLL文件来实现MATLAB与VB的链接,并对圆柱形弹簧变形量进行蒙特卡洛模拟,充分体现MATLAB和VB混合编程的优越性.经计算验证,运算效果较为理想.
