“…Smit and Bronsvoort [4] proposed a paradigm in 2009 by extending the multiple-view feature modeling concept to the scope of analysis, adding an analysis view to a multipleview feature modeling system. A further study should be done on the "link" between the design and analysis models, which can maintain both models simultaneously and keep them consistent in a way that if one is modified, its changes are propagated to another.…”

Many complex mechanical products can be considered as multibody systems; 3D computer-aided design (CAD), multibody dynamics, finite element-based strength and fatigue analyses, optimization, and other CAE tools, are often used to develop this kind of product. But design is difficult and challenging because of information inconsistence among different engineering domains, and isolated information model islands exist. Lots of research are attracted to design and analysis information integration, but attentions are mainly focused on integration of CADfinite element analysis (FEA), supporting the bottom-up design principle, while multibody dynamics analysis for analyzing global performance of a mechanical system is rarely considered, which follows the top-down design principle. In this paper, a novel multilevel system representation modeling framework for supporting both bottom-up and top-down or mixed design methods is proposed. It can integrate the product design CAD models with multibody dynamics, finite element-based strength and fatigue analyses, realizing a CAD-dynamic-FEA-fatigue analysis integration. It can also support data exchange and transfer in multidomain analyses. The framework is illustrated with a case study of a load haul dump (LHD) design using currently available software tools. Furthermore, a design case study of the working unit of the LHD is given to highlight the applicability of the modeling framework for multibody mechanical systems. It has been demonstrated that the framework can describe information exchanging and integration among CAD, FEA-based strength and fatigue analyses, and multibody dynamics analysis during a multibody mechanical product design process.

“…For most commercial CAD software, the focus is usually on the two processes which are considered as two independent activities and not well integrated [4]. Though the design and analysis models in essence describe the same object, the models are so *Address correspondence to this author at the School of Mechanical Engineering, Dalian University of Technology, Dalian, Liaoning, 116024, P.R.…”

Current parametric parts library cannot contribute to the reuse of finite element model. It is essential to remodel or exchange model for parts in CAE software. This paper presents a synchronous CAD/CAE modeling method, which can be employed in parts library based on Siemens NX software. Primary CAD and CAE information in part are merged into master model, which acts as cornerstone for solid model, FE model and simulation model. Thus, part models from parts library can be directly used into simulation analysis, and parametric amendment and change propagation is sustained. A software package developed for designers is helpful to search and achieve desired part from parts library. Three case studies are carried out to clarify synchronous CAD/CAE modeling process and change propagation procedure.

“…In order to transfer various finite element attributes between different models, residing in different packages, it is essential that the various models are robustly linked [7,16]. The ability to relate different meshes back to the same design model provides tighter integration between the disciplines.…”

Abstract. Integrating analysis and design models is a complex task due to differences between the models and the architectures of the toolsets used to create them. This complexity is increased with the use of many different tools for specific tasks during an analysis process. In this work various design and analysis models are linked throughout the design lifecycle, allowing them to be moved between packages in a way not currently available. Three technologies named Cellular Modeling, Virtual Topology and Equivalencing are combined to demonstrate how different finite element meshes generated on abstract analysis geometries can be linked to their original geometry. Cellular models allow interfaces between adjacent cells to be extracted and exploited to transfer analysis attributes such as mesh associativity or boundary conditions between equivalent model representations. Virtual Topology descriptions used for geometry clean-up operations are explicitly stored so they can be reused by downstream applications. Establishing the equivalence relationships between models enables analysts to utilize multiple packages for specialist tasks without worrying about compatibility issues or substantial rework.
