了得網工業技術_3D立體顯示鑄造過程模擬仿真案例集（配光盤）

編輯推薦

本書搜集整理了作者十幾年來的鑄件模擬仿真算例，進行了基於紅藍的3D顯示處理，展現給讀者，從中可以看到鑄件模擬仿真中的STL表面離散網格、有限差分網格以及充型過程、溫度場、應力場、位移、縮孔縮松等各種模擬結果。從中可以借助3D立體顯示更好地觀察鑄件的形狀結構和各種模擬仿真結果的細節以及典型鑄件鑄造過程中的充型流動、冷卻、收縮缺陷和應力變形規律，體會出3D立體顯示技術在復雜鑄件模擬結果顯示與分析中的優越性。3D立體顯示技術是模擬仿真前後處理顯示的方向，在不久的將來必將獲得飛速發展。本書還附了紅藍眼鏡和光盤，光盤收錄了書中圖像文件及靜態圖片難易展現的動畫文件，這些可以借助於常規播放設備，佩戴紅藍眼鏡觀察即可。

內容簡介

《3D立體顯示鑄造過程模擬仿真案例集》為典型鑄件鑄造過程數值模擬算例集，包括發動機缸體、汽輪機缸體、水輪機葉片、導葉、鑄錠等，涵蓋了鑄鐵件、鑄鋼件、鑄鋁件和鋼錠，模擬結果包括溫度場、流場、應力場、位移場、應變場，預測的缺陷包括縮孔縮松、裂紋、變形等。

本書還包括了個別鑄件熱處理過程的算例以及組芯造型裝配的算例。所有模擬結果圖片經過了紅藍效果的3D立體處理，因此給讀者展現的是躍出紙面的立體模擬結果，對觀察、理解和分析模擬結果具有很大幫助，這不同於傳統的印刷顯示效果，是本書的一大特色。另外，書中還附有光盤，其中包括書中紅藍立體圖片和動畫演示，可在任何播放圖片和視頻的硬件下播放或投影，內容更豐富，效果更佳。

本書可以為鑄造專業人士進行鑄件凝固過程數值模擬作參考，也可以用於鑄造領域本科和研究生教學，作為參考書。

前言

前言

Modeling and simulation for castings has been prospering from 1980’s. Currently, there are about a dozen popularly used commercial software and also some software and programs used for research purpose. Although 3D stereoscopic display technology is coming into more and more common use in the field of entertainment such as movies and games, this technology is fresh in industry and scientific research. Ten years ago, Prof. Liu Baicheng deemed that it must be a tendency of its application in the area of modeling and simulation, and installed a big grating 3D Display. In recent years, we have developed the new 3D stereoscopic display system for the modeling and simulation of casting process.前言

Modeling and simulation for castings has been prospering from 1980’s. Currently, there are about a dozen popularly used commercial software and also some software and programs used for research purpose. Although 3D stereoscopic display technology is coming into more and more common use in the field of entertainment such as movies and games, this technology is fresh in industry and scientific research. Ten years ago, Prof. Liu Baicheng deemed that it must be a tendency of its application in the area of modeling and simulation, and installed a big grating 3D Display. In recent years, we have developed the new 3D stereoscopic display system for the modeling and simulation of casting process.

A dozen of typical casting case studies are organized from the twenty years of research experience, all of the simulated results were treated into red-cyan pictures and movies for 3D display in this book. The contents including the STL meshes, finite difference meshes and finite element grids, and the simulated results of solidification process (shrinkage/porosity and fluid flow during mold filling, temperature, stress, strain, displacement fields). By the 3D pictures and movies (provided in the CD-ROM), the detailed results can be more easily observed, especially for complicated castings. 3D stereoscopic visualization represents the tendency of display technology in the future although there is inconvenience by glasses-aided viewing.

In this album, a CD-ROM is attached, which includes the 3D pictures in the book and 3D movies. The album can be read and the electronic files can be displayed on nearly all traditional media, 3D effect can be felt as you wear the red-cyan glasses folded in the album.
