材料力学虚拟仿真实验系统的开发

Research and development of virtual experiment system of material mechanics

用Visual Basic 6.0系统开发了材料力学虚拟仿真实验系统。该系统采用图形用户界面、选单和对话框驱动,通过对话窗口选择梁的类型、横截面形状、尺寸以及荷载类型、大小等参数,在窗口实时显示变形、剪力和弯矩。该系统还可测量不同位置的挠度和内力、查询不同位置梁的内力方程和挠曲线方程的系数,并得到准确数据。虚拟仿真实验将抽象概念用图形显示出来,有利于学生对材料力学概念的理解和掌握。

Abstract：A virtual experiment system of material mechanics was developed by Visual Basic 6.0.The system was driven by Graphical User Interface（GUI）,menu and dialog box.The type and sizes of beam,the type and sizes of beam section,the type and amplitude of loading and so on,were selected and inputted in dialogue windows. The deformation,shear force and moment diagram were displayed in windows simultaneously.The exact displacement and internal force at any position can be measured.The concrete coefficients of equations of deflection curve and internal force equations at any segment of beam can be gotten.Abstract concept was expressed by graphics visually using virtual experiment,which is benefit for student to understand and master the concept of material mechanics.
