基于MATLAB和VB的振动仿真系统的开发及应用

Development and application of vibration simulation software based on matlab and visual basic

介绍了运用Matlab和VB的ActiveX技术进行混编机械振动系统可视化软件的构成及其使用方法,实现了对从常见的单自由度到多自由度以及连续系统的可视化运动学仿真,通过VB读取输入窗口的数据并写入文件来生成Matlab的M文件,并通过在VB中编写程序导入Matlab主窗口中的可执行程序来获得可变参数的Matlab数值解,从而方便、快捷地获得模型系统的各阶模态、时域特性、频域特性等一系列可视化数值解。结合了双摆实例对其相关模块的建立与使用进行了详细说明。

It introduces the components and the methods of using Mechnical Experiment software, which was set up by Visual Basic program and ActiveX technology. This software realize the visual kinematics simulation of systems form Single Degree-Of-Freedom to Multi-Degree-Of-Freedom and also Continuous. The program will read and write data files to generate the Matlab file,and import procedures for the main window to gain variable numerical solution. We can easily attain some numerical solution of Mode,Forced Response and Frequency Characteristics and so on. It shows the details of establishment and using methods of the double pendulum.
