product Data Model for Performance-driven design

Chinese Journal of Mechanical Engineering 2017年第5期30卷 1112-1122页

When designing large-sized complex machinery products, the design focus is always on the overall per- formance; however, there exist no design theory and method based on performance driven. In view of the defi- ciency of the existing design theory, according to the performance features of complex mechanical products, the performance indices are introduced into the traditional design theory of ＂Requirement-Function-Structure＂ to construct a new five-domain design theory of ＂Client Requirement-Function-Performance-Structure-design Parameter＂. To support design practice based on this new theory, a product data model is established by using per- formance indices and the mapping relationship between them and the other four domains. When the product data model is applied to high-speed train design and combining the existing research result and relevant standards, the corresponding data model and its structure involving five domains of high-speed trains are established, which can provide technical support for studying the relationships between typical performance indices and design parame- ters and the fast achievement of a high-speed train scheme design. The five domains provide a reference for the design specification and evaluation criteria of high speed train and a new idea for the train＇s parameter design.

A Multidisciplinary Optimization Architecture for A Distributed Computing Environment

引用

International Journal of Plant Engineering and Management 1998年第1期3卷 50-57页

作者： Ou Song, Zhong Muliang, Mao Zongyuan and Zhou Qijie Department of Automatic Control Engineering, South China Univ. of Tech. Guangzhou, 510641, P.R. China

This paper introduces a distributed computing approach for multidisciplinary complex product design. The framework that may aid in the implementation of this scheme is described. This distributed design environment has the property of concurrent engineering. The approaches considered here are the framework of a distributed optimization design environment and the optimization architecture in the environment.
