摘要：This study investigated the relationship between a subject’s evaluation of injection molding machines (IMMs) and formal design features using Kansei engineering. This investigation used 12 word pairs to evaluate the IMM configurations and employed the semantic differential method to explore the perception of 60 interviewees of 12 examples. The relationship between product feature design and corresponding words was derived by multiple regression analysis. Factor analysis reveals that the 12 examples can be categorized as two styles—advanced style and succinct style. For the advanced style, an IMM should use a rectangular form for the clamping-unit cover and a full-cover for the injection-unit. For the succinct style, the IMM configuration should use a beveled form for the safety cover and a vertical rectangular form for the clamping-unit cover. Quantitative data and suggested guidelines for the relationship between design features and interviewee evaluations are useful to product designers when formulating design strategies.

摘要：Based on the idea of "bearing function separation", a structural member called shock absorber that makes use of its plastic deformation is presented for reducing the seismic response of the bridge. The design criterion for matching material stress, strain and earthquake fortification aim, is also given. The analysis results show that the high speed railway box girder with the absorber in this paper has great reduction effect in seismic response of the bridge piers.

摘要：In this study, control factors which included aspect ratio of fibres, volume fraction of fibres and fibres orientation were the focus for determining the optimum tensile strengths of coir fibres reinforced polyester resin composites. After using Archimedes principle to determine the volume fraction of fibres, tensile test was conducted on the samples of treated and untreated coir fibres reinforced polyester resin composites, respectively. For the optimum properties to be obtained, a Universal Testing Machine-TUE-C-100 was used for the conducted tensile tests which established the levels of control factors settings for quality characteristics needed to optimize the mechanical properties being investigated. Applying Taguchi robust design technique for the greater-the-better, the highest signal-to-noise ratio (S/N ratio) for the quality characteristics being investigated was obtained employing Minitab 16 software. The optimum values of the control factors were established for treated coir fibres reinforced polyester resin composites and untreated coir fibres reinforced polyester resin composites. The treated coir fibres reinforced polyester matrix composite has the optimum tensile strength of 42.7 N/mm2 while the untreated coir fibres reinforced matrix composite has the optimum tensile strength of 21.9 N/mm2. The reinforcement combinations of control factors contribute greatly to the tensile properties, and the treated coir fibres reinforced polyester composites are stronger in tension than the untreated coir fibres reinforced polyester composites.

摘要：目的:非矩形平面框架致使其交叉斜撑体系具有非对称性,而采用了非连续支撑的非对称非连续交叉支撑体系的面外稳定问题更为复杂。本文旨在通过建立无量纲稳定特征方程,从理论上深入阐释该交叉支撑体系的面外屈曲特征,并为工程设计提供显式的压杆计算长度系数的计算公式。创新点:1.建立一般情况下非对称非连续交叉斜撑体系的无量纲特征方程;2.针对各种可能受力工况,详细分析该交叉支撑体系的面外屈曲特征,并给出理论解释;3.提出非对称非连续交叉斜撑体系中压杆计算长度系数的显式经验计算公式。方法:1.通过对非对称非连续交叉支撑体系进行弹性面外屈曲建模,以及稳定平衡方程的无量纲化,推导出其相应的特征方程;2.通过变量替换,揭示其内在对称性,从而为经验公式的构造提供依据;3.针对各种受力工况,进行求解域分析和确定,完成特征方程的求解,以进行面外屈曲特征分析,并提出压杆计算长度系数的经验公式;4.利用经验公式对多个实例进行计算,并与基于有限元的刚度法结果以及以往的文献数据进行比较,以验证经验公式的可靠性。结论:1.推导出了非对称非连续交叉斜撑体系的特征方程;采用无量纲参数后,该方程具有一般性。2.通过变量替换,该方程可以转换为与单轴几何对称交叉斜撑相同的特征方程形式。3.当交叉斜撑中的连续杆和非连续杆同时受压时,非连续杆将率先失稳。4.针对各种受力工况,提出了交叉支撑体系的压杆计算长度系数的显式经验公式,且计算结果兼具可靠性和准确性。

摘要：三维空芯定向刨花板是一种新型的夹芯板,应用于木结构建筑中,可以有效地减轻墙体重量,简化墙体制造工艺,然而冲击性能是衡量结构性能的重要指标。笔者针对三维空芯定向刨花板、泡沫填充三维空芯定向刨花板进行低速冲击测试,对板材冲击力,位移和能量进行了比较研究。研究结果表明,三维空芯定向刨花板组成单元、三维空芯定向刨花板及泡沫填充三维空芯定向刨花板之间冲击性能差异显著;表板和三维定向刨花板芯板抗冲击力最大,三维空芯定向刨花板破坏位移最大;泡沫填充大大减少了三维空芯定向刨花板的抗冲击力和破坏位移,增加了冲击能量。

摘要：This paper presents four different hybrid genetic algorithms for network design problem in closed loop supply chain. They are compared using a complete factorial experiment with two factors, viz. problem size and algorithm. Based on the significance of the factor “algorithm”, the best algorithm is identified using Duncan’s multiple range test. Then it is compared with a mathematical model in terms of total cost. It is found that the best hybrid genetic algorithm identified gives results on par with the mathematical model in statistical terms. So, the best algorithm out of four algorithm proposed in this paper is proved to be superior to all other algorithms for all sizes of problems and its performance is equal to that of the mathematical model for small size and medium size problems.
