虚实并举的可交互过程在工程设计教学中的应用研究

Research on the Application of the Interactive Process of Virtual Reality in Engineering Design Teaching

在工程设计教学过程中,以往的动画或者实验演示视频教学,是既不能打开操作,又不能从外部直接观察其内部状态的系统.文章使用虚实并举的可交互过程,根据所设定的地层和施工参数,通过软件对压裂模型进行选择,并计算得到最优压裂几何形状,可以将"黑箱问题"转化为"灰箱问题",对参数进行直接修改.通过该虚拟仿真实验教学系统,可以使学生直观地看到参数变化对水力压裂的影响.通过虚实结合的可交互过程,既可以展示设计内容的直接效果,又得到了教学讲授相关的计算原理及应用效果,使学生深入理解工程设计与应用过程.

In the course of engineering design teaching,the previous animation or experimental demonstration video teaching can neither open the operation nor directly observe the internal state of the system from the outside.In this paper,according to the formation and operation parameters set,the fracturing model is selected by software,and the optimum fracturing geometry is obtained by using the interactive process of virtual reality.The "black box problem" can be transformed into "grey box problem".Directly modify the parameters.Through the virtual simulation experiment teaching system,students can see directly the influence of parameter change on hydraulic fracturing.Through the interactive process of the combination of real and virtual,we can display the The direct effect of calculating content has also obtained the calculation principle and application effect related to teaching and teaching,which makes the students understand the engineering design and application process deeply.
