Quality control is very important in the manufacturing process of cold tube-bending, but most of enterprises can only verify tube quality by the tube bending machine. Based on the platform of commercial software, an integrated system on CAD/CAPP/CAE for bending tube in power plants boiler is developed. The system is carried on re-development under the VC++ language environment, and data is transferred in Pro/E, Ansys and designing module through a reasonable data structure and interface. So we can share data and realize flexibility and standardization of the processing. The application result indicated that the integrated system can offer a whole set of solution from building a CAD model, forecasting tube bending quality and structure optimization by CAE methods to programming CAPP processes.

This article describes the proposed approaches to creating distributed models that can, with given accuracy under given restrictions, replace classical physical models for construction objects. The ability to implement the proposed approaches is a consequence of the cyber-physical integration of building systems. The principles of forming the data structure of designed objects and distributed models, which make it possible to uniquely identify the elements and increase the level of detail of such a model, are presented. The data structure diagram of distributed modeling includes, among other things, the level of formation and transmission of signals about physical processes inside cyber-physical building systems. An enlarged algorithm for creating the structure of the distributed model which describes the process of developing a data structure, formalizing requirements for the parameters of a design object and its operating modes (including normal operating conditions and extreme conditions, including natural disasters) and selecting objects for a complete group that provides distributed modeling is presented. The article formulates the main approaches to the implementation of an important practical application of the cyber-physical integration of building systems - the possibility of forming distributed physical models of designed construction objects and the directions of further research are outlined.
