摘要
以 VC+ + 6 .0为开发工具 ,将 UNIX环境下的离散元程序进行了移植和改造 ,研制出在微机WINDOWS环境下的离散元仿真程序。程序的计算和控制部分采用混合编程、动态链接及多线程编程技术 ,在可视化图形程序设计中成功地引进了 Open GL图形库 ,实现了图像资料直接打印和保存。使用上述程序模拟了急刹车情况下车载散体与车厢的相互作用 ,表明新程序的操作和图形显示界面友好 。
The code of Discrete Element Method used for simulation of particulate materials with a UNIX platform was recoded and transplanted to PC computers with WINDOWS platform. During programming, several advanced techniques, such as mixed language programming, multithreading, dynamical link libraries and database were utilized. OpenGL graphics library was introduced to draw graphics, which can be saved or printed out conveniently. Test was done for the response of granular materials filled within a truck containner during a sudden breaking. The result showed that the new program has a friendly control interface and a high graphing performance with high computational efficiency.
