The operation purpose: working out of effective methods of the analysis of dynamic processes in machine assemblies and bearing the metalwork, the dynamic forces directed on lowering in elements of machine assemblies, and also levels of vibrations of the process equipment and buildings. Methods of researches. Calculations of free and harmonic forced vibrations in mechanical systems with the concentrated and arranged performances are executed with use of a matrix method of initial parametres. For definition of strains and internal force are used analytical and numerical methods of the solution of the differential equations. The analysis of nonstationary operating modes of machine assemblies is spent by mathematical simulation taking into account continuous interconnection of the electromagnetic phenomena in propellers, control systems and the mechanical oscillating phenomena in machines. Results НИР are introduced in educational process at teaching of disciplines "Strength of materials" and "the Automized calculation of building constructions by a finite element method", in particular, in the form of methods and algorithms of definition of voltage elements of machines and buildings taking into account dynamic loads.
