OPTIMIZATION PROBLEM SOLVING For SPATIAL STRUCTURES
In the paper there are described issues related to the determination of the total time estimated for optimization process of dynamic spatial structures with different degrees of freedom. Structures constitute the systems of rigid bodies elastically connected with each other and the base of with tree-like structure. An algorithm is presented to simplify the analytical expressions for calculating the triple sum included in the differential equation for determining the generalized coordinates. The algorithmic programming language is chosen, the problem of parametric optimization of constructions is set. Time graphs for a single numerical integration of systems of differential equations depending on the dynamic process duration and the maximum natural frequency of systems oscillations for structures with different degrees of freedom are obtained. The analysis of possibility for determination of the same local minima of the generalized criterion at consecutive and parallel computing processes of structure optimization is carried out, reduction of calculation time is defined at parallel calculations with use of multi-core processors of PC.
