This WMADF allows designers to develop web -based computer aided programs in a systematic way during the collaborative mec hanical system design and analysis process. This system is based on an emerg ing web-based Content Management System (CMS) called eXtended Object Oriented P ortal System (XOOPS). Due to the Open Source Status of the XOOPS CMS, programs d eveloped with this framework can be further customized to satisfy the demands of the user. To introduce the use of this framework, this paper exams three differ ent types of mechanical design and analysis problems. First, a repetitive design consideration and calculation process is transferred into WMADF programs to gai n efficiency for wired collaborative team. Second, the considered product solid model is created directly through the use of XOOPS program and Microsoft Compone nt Object Model (COM) instances. To the end of the paper, an example linked with ANSYS is used to indicate the possible application of this framework.展开更多

Unfortunately, because tribology design knowledge is often m ulti-disciplinary,complicated and piecemeal, it is therefore difficult for a mechanical designer to capture the neededtribology design knowledge. The concept of tribology design repository is proposed in this paper totry to address this problem. This paper presents an object-oriented knowledge representation lan-guage based on the modeling of tribology design component and it makes the complicated tribol-ogy knowledge represented has such advantages as inheritance, encapsulation, and consistency.A web-based triblogy design repository is then established and it enables the edition, retrieve,sharing and reuse of corporate tribology design knowledge in the repository from the Internet.展开更多

However, the Web application quality is improving slowly, which requires efficient methods for devel- oping Web systems. This study presents a model for Web-based software development for analysis and design phases based on the ISO/IEC 12207 standard. It describes the methods used to define processes and entities in order to reflect the contents in Web applications. It applies the methodology of Web-Road Map by KCC Information and Technology using this model to the public project. As a result, Web-Road Map is proven to be an efficient model to analyze and design Web-applications.展开更多
主观评价和客观测试是研究环境热舒适性的主要方法,一般的客观测试是通过布置测点测试室内热环境参数计算预计平均热感觉指数(PMV——Predicted Mean Vote),室内热环境的非稳态影响因素使得该方法很难综合描述并准确预测非稳态热环境下...主观评价和客观测试是研究环境热舒适性的主要方法,一般的客观测试是通过布置测点测试室内热环境参数计算预计平均热感觉指数(PMV——Predicted Mean Vote),室内热环境的非稳态影响因素使得该方法很难综合描述并准确预测非稳态热环境下人的热舒适程度。本文通过中国成年人体数据库获取我国人群的体貌及生理特征,选取50百分位成年男性人体三维数据建立暖体假人模型,根据舒适状态下的人体热平衡方程制定控制策略,开发了一套可用于测试非稳态、非均匀热环境下人体与环境之间热量交换的暖体假人测试系统,在人工环境实验室营造特定的热湿环境,利用暖体假人测试系统测试了当前环境的预计平均热感觉指数(PMV)为-0.8,并对该环境进行被试者主观评价测试,得到热感觉投票值(TSV——Thermal Sensation Vote)为-0.65,被试者主观体验结果与暖体假人客观测试结果的相对误差仅为2.1%。展开更多
