Моделі ідентифікації механізмів паралельної структури

Abstract

The substantiation of the possibility of modeling objects based on signatures, which represent the image of the mechanism of a parallel structure in the form of the natural oscillation spectrum of structurally connected actuators and executive links, is presented. It is shown that the dynamic properties of rod structures describing objects with a finite number of degrees of freedom and variable load distributions on them can be represented by equations that are frequency equations of natural oscillations of a system of mechanisms of a parallel structure. Based on a qualitative ana lysis of the accuracy and adequacy of identification dynamic models and the use of the mathematical appara tus of neural networks, it was concluded that it is preferable to assess the adequacy of identification models in comparison with their accuracy. The results of experimental studies of the signatures of some configurations of the mechanisms of the parallel configuration are presented.
