INFLUENCE OF GEOMETRIC DEVIATIONS ON THE STRESS-STRAIN STATE OF OVERBRIDGE AT TAILINGS THICKENER

Introduction. The article presents the results of testing a developed methodology for assessing effect geometric deviations on stress-strain state metal structures an overbridge at facility «Tailings Thickener 1», located Natalka Mining Processing Plant. A brief review previously performed studies recording is provided, along with confirming relevance problems solved in and study general. It was substantiated that it necessary to adjust project thickener (OT); applicability demonstrated. Aim. In article, determining frame tested light deviations, using example OT. Materials methods. following materials methods were used: – finite element method implemented SCAD 11.5 applied numerical (OT) having deviations; theory dimensional chains modeling authoring software entitled «Dimensional analysis rod structures» Computational Complex used determine values deviations. Results. presented allowed timely substantiation amendments documentation increase reliability economic efficiency OT, as well entire facility. During research: possible OT forecasted, plotting limiting nodes three directions ( X, Y, Z ); included its verification calculations, which necessity adjusting optimizing made decisions; permanent temporary loads reduced, emergency situations be avoided. Conclusions. validated thickener, taking into account accumulation during manufacture installation.
