目的 建筑与工业产品的低碳设计策略有明显差异,其中由属性差异衍生出不同的设计形式。将低碳设计与对象属性的联系作为研究目标,提出在产品设计中,对象属性决定低碳设计形式的假设。方法 将建筑“高技化”与产品“物联网化”进行比较研究,探明其中的联系。基于系统理论从整体性、相关性、动态性、目的性、层次性五个方面进行分析,得出两类人造物在属性上的差异。基于系统设计中的功能、输入输出、程序与层次、环境、媒介及人六个方面,最终形成六个对比因子。以此判断低碳设计与对象属性间的联系,进而解释其设计表象上的差异。结果 对象属性决定低碳设计的形式。结论 对象属性对“功能”“能量转换”“环境”“媒介”四个设计因子产生影响,而对“人”和“程序”两个设计因子不产生影响,设计“人”和“程序”两个因子的方法带有普适性。 相似文献

Indirect Inverse Substructuring Theory for Coupling Dynamic Stiffness Identification of Complex Interface Between Packaged Product and Vehicle Transport System 下载免费PDF全文
Inverse substructuring method has been recently proposed and applied for inverse analysis of the dynamical response of product transport system. The component‐level frequency response functions (FRFs) and the coupling dynamic stiffness for facilitating the cushioning packaging design are all predicted from only the system‐level FRFs. However, the system‐level FRFs from coupling degree of freedoms may not be measured accurately because of the difficulties of vibration excitation and response measurement for the coupled interface between packaged product and vehicle within the limited accessible space. The aim of this paper is to develop a new FRF‐based indirect inverse substructuring method for the analysis of the dynamic characteristics of a three‐substructure coupled product transport system without measuring system‐level FRFs at the coupling degree of freedoms. By enforcing the dynamic equilibrium conditions at the coupling coordinates and the displacement compatibility conditions, a closed‐form analytical solution to inverse sub‐structuring analysis of multi‐substructure coupled product transport system is derived based on the relationship of easy‐to‐monitor component‐level FRFs and the system‐level FRFs at the coupling coordinates.. The proposed method is validated by a lumped mass‐spring‐damper model, and the predicted coupling dynamic stiffness is compared with the direct computation, showing exact agreement. Then, the FRF tests of a physical prototype of multi‐substructure coupled product transport system are performed to further check the accuracy of the suggested method. The method developed offers an approach to predict the unknown coupling dynamic stiffness from measured FRFs purely. The proposed method may help to obtain the main controlling factors and contributions from the various structure‐borne paths for product transport system.

Information technology has promoted our society gradually into knowledge economy from product economy. Value creation requires more and more knowledge and information to support enterprise activities. Knowledge management (KM) as an activity has already existed, and will make the organisation and individual have stronger competition strength, and make better decisions. In order to respond to the industrial trend towards knowledge management, this paper investigates and proposes a framework for product lifecycle knowledge management that utilises product maintenance data across the lifecycle of the product. A case presented in this paper is a maintenance knowledge service system to prove the framework method. 相似文献
