【摘要】 地下厂房可视化设计技术及其计算机仿真是当前仿真研究的主要方向之一。本论文以构建数字三维地下厂房,以及管道、电缆、设备虚拟设计和装配为目标,在CATIA平台基础上,通过二次开发实现了地下厂房的可视化CAD设计,完成地下厂房数字化建模,构建地下厂房可视化设计与仿真系统。主要取得如下成果: 1.基于CATIA参数化设计思想,结合地下厂房设计规范的要求,利用参数化技术和特征建模技术,通过CATIA平台及其提供的二次开发工具,把设计知识转换为显式的参数知识,实现地下隧道典型截面库、特征库的建立。 2.利用组件技术,结合地下厂房典型部件的设计过程和思想,创建地下厂房部件的用户自定义特征。 3.针对压缩管道、通风管道、电缆等管道系统的布局特征,开发智能管道系统的布局特征,并实现管道展开与材料清单统计。 4.针对地下洞室群施工复杂,难以用数学模型表示的特点,提出“拟实体”的概念;采用特征建模技术,简化建模和各种误差数据存储的工作;地下厂房拟实体建模技术与基于拟实体的属性信息管理相结合;实现施工进度优化与拟实体相结合的可视化仿真系统设计。 5.基于上述研究,在考虑地下厂房系统空间关系情况,进行设备布局与优化,并进行系统开发。更多还原

【Abstract】 The visualization design and computer simulation on the underground powerhouse is one of the most important technologies of simulation. In this thesis, the central aim is to construct three-dimensional numeric underground powerhouse and realize the quick design and assemble of piping, cable and equipment. Based on the flat roof of CATIA, this thesis has realized the visualization design of underground powerhouse, accomplished the numeric modeling of the underground powerhouse, and constructed the system of visualization design and excavation simulation by secondary development.1. Based on parameters design of CATIA and the underground powerhouse design requirements, uising parameter technology and feature modeling, the knowledge of the design progresss is converted to visual parameters and the section storeroom and feature storeroom are established.2. Using component technology and according to the design progress of the represatitive components of the underground powerhouse, the user-defined features are constructed.3. Aiming at the character of compressed pipe, vent-pipe, cable and so on, the user defined features about automatic distribution are constructed the Statistic of material bill is realized.4. Because the construction of underground powerhouse and it can not be described in mathematics model, the dummy body is put forward;feature modeling is used to predigest the word of modeling and the storage of data;the dummy body modeling technology is combined with the management of the attribute information based on dummy body;the system including the optimization of construction and the visual simulation is constructed.5. Based on these studies and considering the relationship of plant systems space, the layout of equipment is done and optimized and the system is developed.更多还原
