Given the present gap between CAD and CAE, designers are often hindered in their efforts to explore design alternatives that ensure new product vitality. This paper describes the STEP/EXPRESS based architecture - a design-analysis strategy that views CAD-CAE (FEA) integration as an information-intensive mapping between design models and analysis models. This paper illustrates the implementation of the above-mentioned approach for integrating CAD-CAE (FEA). It is based on an in-depth analysis of the structure, manufacturing technology, and the final structural and mechanical properties of a railway wheel. The forged and pressed pieces form the basis for manufacturing highly-stressed parts, whose strength and fatigue characteristics substantially influence the service life and reliability of the whole construction. The creation of a new product requires very close collaboration between designers, material engineers and manufacturers. Each of them nowadays uses various computer programs, i.e. CAx systems - CAD systems for designing the tools and product, FEA systems for mathematical modelling technological operations used in forming and simulating the product's behaviour during use, or manufacturers of NC machines for producing die blocks, etc. The compatibility of shared or interchanged data in electronic form represents an obstacle to this collaboration. The authors of this paper would like to demonstrate that contemporary computer science offers a solution to this problem: Suitable information technology for integrating these mostly independently developed software applications using data models STEP/EXPRESS.
