基于Unity3D的液塑限含水率虚拟实验设计与实现

Design and Implementation of the Virtual Experiment for Liquid and Plastic Limit Moisture Content Based on Unity3D

针对细粒土液塑限含水率试验在土力学课程教学中的重要性,以及重复开设课堂实验的局限性,基于Unity3D平台开展虚拟实验的设计和开发,实现随机测试样本的液塑限含水率虚拟实验。该虚拟实验能逼真模拟实验室三维场景、仪器设备及操作流程,提升实验体验真实感;通过测试样本多参数的随机组合,生成随机测试样本,避免实验结果的重复性;实验操作过程中的人机交互设计能实现理论知识和实验要点的考核,提升虚拟实验的辅助教学功能。

In view of the importance of the liquid and plastic limit moisture content experiment of fine-grained soil in the teaching of soil mechanics,and the limitation of repeated test classroom experiments,the virtual experiment design and development is carried out based on Unity3D platform to realize the virtual experiment of the liquid and plastic limit moisture content experiment for random test samples.The virtual experiment of liquid plastic limit moisture content can realistically simulate the three-dimensional scene of the laboratory,equipment and operation process and can enhance the sense of reality of the experimental experience.With random combination of multi parameters of test samples,random test samples are generated to avoid the repeatability of experimental results.And the human-computer interaction design in the experimental operation process can realize the assessment of theoretical knowledge and experimental points,and improve the auxiliary teaching function of virtual experiments.
