【摘要】：本文以H2-1型滑动轴承实验台为研究对象,提出了一种建立网上虚拟平台的思路:即在虚拟建模语言VRML的基础上,结合Solidworks三维建模软件,实现滑动轴承实验台的虚拟建模,达到感性交互的效果;同时利用MATLAB GUI编写实验数据分析界面,达到理论验证的目的。主要的研究内容及结果如下: 1.综合利用VRML和Solidworks的建模功能,采用Solidworks建立滑动轴承三维实验平台模型,以“*.wrl”结尾的VRML网页文件导入VRML环境。通过Shape节点将空间造型的几何尺寸和外观结合起来,利用Appearance节点定义造型外观的颜色和纹理,分别建立滑动轴承实验台的零部件,并装配成完整的整体模型。 2.为了达到真实的实验情境,充分发挥VRML语言的多媒体功能,虚拟平台中加入了声音、图像、动画等多媒体效果;同时依靠时间传感器TimeSensor创建虚拟时钟,并对滑动轴承主轴切点发送时间值,控制主轴在VRML空间开始运转、变化和结束的时间; 3.采用Matlab语言编写人机交互界面,通过添加窗口菜单、文本框、坐标轴、按钮等各类控件来设计独具特色的图形界面,然后编写回调代码来实现控件功能。实验者可以通过选中或者激活这些对象而使系统执行某种用户需要的动作,如通过改变径向滑动轴承参数(宽径比、偏心率等),绘制不同油膜压力分布曲线,揭示油膜压力曲线形状的变化规律,帮助学生加深对滑动轴承实验的理论理解。
[Abstract]:In this paper, the H2-1 sliding bearing experimental platform is taken as the research object, and the idea of establishing a virtual platform on the net is put forward: based on the virtual modeling language VRML and Solidworks 3D modeling software, the virtual modeling of the sliding bearing experimental platform is realized. At the same time, we use MATLAB GUI to write the experimental data analysis interface to achieve the purpose of theoretical verification. The main research contents and results are as follows:. 1. Based on the modeling function of VRML and Solidworks, the 3D experiment platform model of sliding bearing is established by Solidworks, and the VRML web page file which ends with ".wrl" is imported into VRML environment. The geometric dimension and appearance of space modeling are combined by Shape node. The color and texture of the shape appearance are defined by Appearance node, and the parts of the sliding bearing test table are established, and the whole model is assembled. 2. In order to achieve the real experimental situation and give full play to the multimedia function of VRML, the virtual platform adds multimedia effects such as sound, image, animation, etc. At the same time, it relies on the time sensor TimeSensor to create the virtual clock. And send the time value to the spindle tangent point of the sliding bearing, control the spindle start to run, change and end time in the VRML space; 3.The man-machine interface is written by Matlab language, and the unique graphical interface is designed by adding window menu, text box, coordinate axis, button and other controls. The experimenter can select or activate these objects to enable the system to perform certain actions required by the user, such as by changing the radial bearing parameters (width to diameter ratio). The eccentricity ratio is used to draw the pressure distribution curve of different oil film, to reveal the change rule of oil film pressure curve shape, and to help the students to deepen the theoretical understanding of sliding bearing experiment.
