Abstract

Structure stresses and deformations calculation veracity is determined by the modeling quality depending on how the structure of the design model and the elastic properties of its elements correspond to the structure and elastic properties of the strength elements of the simulated structure. As a result, the complexity of the procedure for the initial data setting (the analysis model), which becomes comparable with the complexity of the design itself in the case of a complex technical object designing, increases significantly. Taking into account the experience of modern computer-aided design systems using, the problem of reducing the computational models synthesis duration of the complex technical objects can be solved using the decomposition method. In this case, there is a problem associated with the need to harmonize the models structures of substructures, without which it is impossible to synthesize a common model of the structure. The process of structures coordinating of many models is associated with the intensive data exchange within the information system. In this case, the size and the structure of traffic substantially depend on the features of the interacting models structures implying a wide variety of data transfer formats. Based on the results of the research, it has been established that canonical data structures supported by the majority of modern DBMS do not allow to effectively managing the process of data exchange between CAE complexes. It is shown that DBMS, using object-oriented information technologies, are the most optimal ones for managing the process of the computational models synthesis of the complex technical objects. At the same time, it is necessary to implement information technology, considered the objects as the active elements operating outside the program modules, to provide the full implementation of data exchange control functions between analysis models.
