Topology optimization could have better optimization efficiency because it can provide the optimized distribution of material and gain optimized structure in conceptual design phase of the structural design. In order to obtain lightweight and high stiffness structure  a truss turntable based on topology optimization of continuum structure is presented  and the validity of this lightweight structure is examined by finite element analysis. Comparing to the traditional welding steel turntable  the lightweight turntable  without changing the static displacement  can lose 386.48 kg(lightweight ratio is 26.7%)  and its first-order natural frequency raises from 167.02Hz to 173.71Hz. Meanwhile  in other aspects this turntable also has better performance than traditional structure. 2012 IEEE.   数值模拟技术在大型铸钢件生产中的应用 期刊论文 2010, 2010 刘小刚; 沈厚发; 康进武; 张雷; 黄天佑; 边敦亭; LIU Xiao; SHEN Hou; KANG Jin; ZHANG Lei; HUANG Tian; BIAN Dun 收藏  |  浏览/下载：1/0 大型轧钢机机架凝固过程温度场应力场模拟分析 期刊论文 2010, 2010 刘小刚; 康进武; 黄天佑; 边敦亭; 张良红; LIU Xiao-gang; KANG Jin-wu; HUANG Tian-you; BIAN Dun-ting; ZHANG Liang-hong 收藏  |  浏览/下载：3/0 80MN快锻机上横梁铸造工艺仿真与优化 期刊论文 2010, 2010 刘艳; 周守航; 张西鹏; 韩庆礼; 石立文; 沈厚发; 李文胜; LIU Yan; ZHOU Shou-hang; ZHANG Xi-peng; HAN Qing-li; SHI Li-wen; SHEN Hou-fa; LI Wen-sheng 收藏  |  浏览/下载：4/0 我国大型铸钢件生产的现状与关键技术 期刊论文 2010, 2010 黄天佑; 刘小刚; 康进武; 沈厚发; 柳百成; HUANG Tian-you; LIU Xiao-gang; KANG Jin-wu; SHEN Hou-fa; LIU Bai-cheng 收藏  |  浏览/下载：3/0 Application of modeling and simulation of thermal stress in solidification process of a heavy steel casting 期刊论文 2010, 2010 Liu Xiaogang; Kang Jinwu; Huang Tianyou; Liu Baicheng 收藏  |  浏览/下载：4/0
