摘要: 以球形蜗杆砂轮磨齿机的床身为研究对象,设计了不同的床身结构作为备选方案,并建立了各方案参数化模型,对其进行了灵敏度分析和多目标优化计算确定其最优尺寸参数,通过对其进行有限元分析获得了优选决策的初步数据。建立了床身优选评价的TOPSIS数学模型,经计算求解优选出最佳方案。对比分析了优选前后床身的静态和动态性能,验证了床身的优选结果的有效性,完成了球形蜗杆砂轮磨齿机床身的优选设计。

Abstract: A spherical worm grinding wheel machine bed wasas research object and several bed structures were designed.The parametric models of each alternative were built and their sensitivity analyses were conducted respectively. The optimal dimensions of each alternative were obtained through multi-objective optimization. The preliminary data was obtained for decision making through finite element analysis of each optimized model. TOPSIS mathematical model of the bed was established and the best alternative was determined according to calculation results. The validity of the preference results was verified compared with analysis results of the original bed. The preference task for the bed of spherical worm wheel grinding machine was completed.

Key words: technique for order preference by similarity to an ideal solution(TOPSIS) method, multi-objective optimization, preference design, sensitivity analysis
