Golovchenko V. Design of bulky welded carrying structures on the base of parametric analysis and synthesis with wind energy conversion systems frames as an example

Solving of an actual and important task of developing of systems for computer-aided design of bulky welded carrying structures is given in the work. The system developed is integration of universal CAD/CAE/CAM-systems with special modulus for creating of current geometric and finite-element models of structures being designed with the aim of their stress-strain state multy-variant analysis, which is to be performed for parametric and structural analysis and synthesis of their elements. The possibility of multy-variant analysis is ensured by the use of parametric description at stages of geometrical, mathematical and finite-element modeling of the structures. High capacity wind energy conversion systems frames serve as an example of the structures under designing. Application of the system developed enabled to perform a stress-strain state analysis of elements of wind energy conversion system frame for "Nordex" firm and to work out rational forms of the elements welded joints
