摘要：The sound insulation performance of railway car body structures is critical for the control of rail vehicle interior *** sound transmission loss(STL)measurements,a niche with a large depth is necessary to allow for mounting the wide range of thicknesses of railway car body panels and for the mechanical isolation of the two *** this study,two typical interior floor panels are tested in a series of mounting conditions and mechanical boundary *** change of STL results during measurement is also predicted by an STL prediction model based on the finite element *** lower frequencies,the STL results are influenced by both the mounting positions and the mechanical boundary *** higher frequencies,the STL results are mainly influenced by the mechanical boundary *** between the panel in the infinite baffle and niches at the resonance and off-resonance frequencies are *** both the effects of mounting positions and mechanical boundary conditions,the existence of the cavity amplifies the STL difference caused by the mechanical boundary conditions.

摘要：This paper presents an investigation into the characteristics of interior noise of a Chinese high-speed train under several typical conditions. Interior noises within Vehicle TC01, which can be used as a head car or an end car, and Vehicle TP03, the third car counting from TC01, are measured for the train running at speeds from 260 km/h to 385 km/h, along two types of track including a slab track and a ballast track and either on the ground surface or in a tunnel. Data analyses are performed for sound pressure overall levels, frequency, area contributions, and possible generation mechanisms, showing how they are affected by train speed, running direction, track type, and tunnel. The results show that, whether TC01 is used as head car or end car, the interior noise characteristics in the VIP cabin are mostly related to aerodynamic noise. Differences in interior noise between tracks become smaller as the train speed increases. The effect of a tunnel on the interior noise is more important for the middle coach than that for the head coach. This study can provide a basis for noise control of high-speed trains.

摘要：简要分析了消失模铸造球墨铸铁件的浇注系统设计及铸造中常见的缩松缺陷的形态、成因及其预防。通过实验发现,铸件上端面及厚大部位出现缩孔、夹渣的缺陷。通过计算和模拟,增加上端面加工余量、增设冒口,配合改进浇注系统,采用近似底注的方式,提高浇注系统的补缩能力,可以预防缩松、缩孔缺陷。对全工序加强过程控制,确定了提高铸件合格率的最佳方案。

摘要：以15641015-3C铝合金变速器壳体为例,对比分析不同浇注系统对铸件质量的影响,并针对缺陷对浇注系统进行工艺优化,减少消失模铸造铸件浇不足、缩松和气孔的现象,提高了变速器壳体铸件的合格率。

摘要：研究秦汉毛笔设计最直接的依据便是散落在各类考古报告之中的客观描述,然而从此欲探究它的历史全貌仍存在诸如论据零散、缺乏整合与现有研究深度不足等疑难。本文在立足于考古简报和文献记载相结合的传统研究基础上另辟新径,从设计学视角探究秦汉毛笔的选材、工艺和形态,力求为毛笔起源的争论提供有益的参考,并凸显秦汉毛笔设计在中国文化史上的地位与价值。

摘要：17-18世纪的欧洲社会,中国瓷器热从宫廷贵族到普通民众持续百年。外销瓷"中国风格"的艺术特色通过瓷画构图及题材类型得以呈现。瓷画中西题材融构一图的现象,体现出设计者文化比较的设计视角,也体现出"中国风格"艺术实现途径中的"非中国性"特征。

摘要：深入挖掘和研究湖笔制售环境的人文内涵,对于探源制笔业日渐凋零,以及促进传统制笔业振兴,都具有重要的意义。因晚清至民国的实物遗存和一手文献资料较为集中和丰富,所以将本文论题研究时期限定于此。在具体写作方面,将从善琏笔业制作、销售、展示、宣传和推广及其相关的笔市、笔舫、笔店等人文环境入手,借助清代文人笔记、民国档案以及实地田野调研,力图突破以往单一研究中的不足,从设计学和造物学双重视角揭示传统毛笔业历史发展中起落相伴的文化现象。

摘要：通过对湖笔相关文献的整理发现,清代湖州笔工群体出现明显分化,即由单一的笔工派生出身份相对独立的笔客和笔商。同时伴随外埠笔庄在19世纪初至中叶的集中创设,一方面使得湖笔影响扩展至全国,另一方面因精英笔工的外流导致原产地善琏由历史上的产销中心转变为货源地。

摘要：关于中国少数民族审美思想的研究,始于上世纪末的90年代。研究的内容横跨人类学、美学、社会学等领域,研究基础是少数民族美学文献和不多的资料,研究重点为民族风情、民族艺术、少数民族文化的传承与创新。自21世纪起,研究内容从横向发展转向了纵深,艺术人类学也介入到了该研究范畴,并且研究领域也予以了扩大,多民族的研究越来越热门,逐步成为一个完整的理论体系。

摘要：本文选取具有江南特色的无锡惠山泥人为研究对象,立足于民艺学和"新民间"艺术的研究成果,阐述了惠山泥人的传统创作观念,从形态、面相、构图样式等方面深入分析惠山泥人创作观念的当代应用,并在材质体量方面进行了新的探索和尝试。
