论文介绍了屈曲分析的定义和屈曲分析有限元分析法,采用有限元分析软件ANSYS建立了天线杆的有限元模型,然后对天线杆进行了线性屈曲分析和非线性屈曲分析,分别求出了屈曲模态及临界载荷,并将分析结果进行对比.对不同的初始缺陷的情况进行屈曲分析,得出临界载荷随初始缺陷的变化规律,分析结果为结构的优化设计提供了理论基础,对类似结构的屈曲分析提供了参考依据. 相似文献

潘天寿作为中国20世纪绘画史上的一面旗帜,一直是当代中国画研究领域的热点,对于他的指墨画研究、艺术教育研究、篆刻画研究等方面的文章不下百篇,其中对潘先生的艺术成就、人格修养、思想观点等各方面做了全面的分析,但是对潘天寿的研究中还存在一些研究者对潘天寿研究欠缺、过多掺杂个人观点以及缺乏时代语境的问题值得我们关注。 相似文献

Research into the use of diagrams is an interdisciplinary endeavour, encompassing disciplines as diverse as psychology, architecture and artificial intelligence. It is also a relatively new research area, with the first meeting of like-minded researchers interested in studying diagrams taking place in 1997. Now that diagrams research is more established, it is timely to review its scope, nature and progress. This paper reviews diagrams research over the past twelve years, as represented in the proceedings of the International Conference on the Theory and Application of Diagrams. In summarising the contents of these proceedings, a taxonomy describing the scope of diagrams research is proposed, the several research issues covered are identified, and the extent to which layout and aesthetics form part of this body of research is discussed. In concluding, trends and under-represented areas are noted and discussed. The aim of the paper is not only to summarise the research covered in this particular conference, but to provide a basis for on-going discussion on the changing nature of diagrams research. 相似文献

Abstract. Critical research in information systems is based on and inspired by ethics and morality. In order to support this proposition, this paper will suggest a way of classifying critical research that differs from definitions common IS research. According to the current definition, research is critical when it is motivated by the intention to change social realities and promote emancipation. Based on this critical intention, critical research is furthermore characterized by critical topics, critical theories, and critical methodologies. Using these criteria of critical research, the paper argues that critical research is ethical in nature. To support this view, the paper introduces the concepts of ethics and morality by analysing two traditions of moral philosophy, here called the 'German tradition' and the 'French tradition'. Using three examples of current critical research in information systems, the paper will show that ethics and morality strongly influence critical intention, topics and theories. Having thus established the ethical nature of critical research, the paper concludes by discussing the weaknesses of critical research from the point of view of ethics and morality. 相似文献

Since the third wave in human–computer interaction (HCI), research on user experience (UX) has gained momentum within the HCI community. The focus has shifted from systematic usability requirements and measures towards guidance on designing for experiences. This is a big change, since design has traditionally not played a large role in HCI research. Yet, the literature addressing this shift in focus is very limited. We believe that the field of UX research can learn from a field where design and experiential aspects have always been important: design research. In this article, we discuss why design is needed in UX research and how research that includes design as a part of research can support and advance UX design practice. We do this by investigating types of design-inclusive UX research and by learning from real-life cases of UX-related design research. We report the results of an interview study with 41 researchers in three academic research units where design research meets UX research. Based on our interview findings, and building on existing literature, we describe the different roles design can play in research projects. We also report how design research results can inform designing for experience methodologically or by providing new knowledge on UX. The results are presented in a structured palette that can help UX researchers reflect and focus more on design in their research projects, thereby tackling experience design challenges in their own research. 相似文献

HCI research has come of age, and now is a good time to reflect upon the HCI research processes that have become established over the years. This paper examines the HCI research process itself with respect to funding opportunities and the methods used for empirical research, assessing in particular the efficacy of standard methods for research dissemination. The focus of the paper is HCI research for older people. The nature of this user group is explored, and Alexandrian patterns are proposed both as a means of dissemination of research results and for strengthening the framework of HCI knowledge. 相似文献
