基于Unity3D的绞吸式挖泥船虚拟仿真系统

Virtual Simulation System of Cutter Suction Dredger Based on Unity3D

为了解决绞吸式挖泥船传统培训方法的一些不足,针对绞吸式挖泥船的施工操作流程和施工环境展示,设计了基于Unity3D的绞吸式挖泥船虚拟仿真系统。针对铰刀切削地形变化的仿真,采取了自动网格变形、贴图变化的方法;配合石块碎裂和管道内泥砂比重的粒子数量模拟,再通过寻路算法实现了2D平面的泥砂路径模拟;通过虚拟交互设备实现立体显示和人机交互,实现更好地虚拟仿真效果。

In order to solve some shortages for the traditional training of cutter suction dredger, a virtual simulation system was designed using Unity3 D, which mainly targeted at operational procedures of construction and display of construction environment. Mesh deformation and texture changing were used to realize the simulation of the soil-cutting. The 2D path simulation which included the simulation of stone crushing and proportion of sand in the pipeline was realized by means of path-finding algorithm. 3D display and human-computer interaction were realized by virtual reality devices, which could improve the effect of the virtual simulation.
