Test Result

In this paper, the structural dynamics study of the frame to support 15MW compressor is suggested. This study used the steel-concrete hybrid frame to support a large compressor system. This paper provided experimental and analytical method to structural design the hybrid frame by considering in rotordynamics and aerodynamics. Dynamic characteristics of the frame have to be identified to tune the finite element model’s boundary condition and to avoid resonance. Therefore modal testing of the frame is performed and boundary conditions are modified applying to the previously obtained modal parameters. While compressor is operated, multiple dynamic loads of compressor, motor and expander may excite on the frame. The total dynamic load is derived by axial aerodynamic load of impeller, radial load of gear and unbalance load of rotor. After dynamic analysis completion, the analysis result is compared with test result to verify the accuracy of analysis. Through this structural dynamic analysis, structural vibration response of hybrid frame can be estimated.

Budget Revenue

The guarantee for stable development of the local community's well-being creates conditions to ensure the financial self-sufficiency for local budgets. Today it is urgent to improve the theoretical and practical approaches to forming the local budget revenue to ensure the necessary financial self-sufficiency level for local budgets. Thus, the purpose of this research is to investigate the level of financial self-sufficiency for local budgets in Ukraine in 1998−2019 by analyzing the revenue side of these budgets. The research used methods of economic, systemic, and structural dynamic analysis. The paper compares different approaches to defining the concept of “financial self-sufficiency for local budgets”. It is determined that the community's success depends on the level of its financial self-sufficiency, which is possible only when the community has financial resources fully to implement local budgets in terms of expenditures. Structural and dynamic analysis of the local budget revenue in Ukraine for 1998-2019 is carried out to assess the level of financial self-sufficiency for local budgets in Ukraine as a whole. The study results indicate the state measures correctness in the reforming of the local taxation system in 2010 and budget decentralization in 2015. However, these measures must be fully implemented and systemic. Conclusions: the composition and structure of the revenues of the local budgets are continually changing, due to the constant changes in the tax system of Ukraine and the state’s efforts to solve the problem of generating local budget revenues, not due to the development of local taxation, but via official transfers. In such conditions, the self-sufficiency of local budgets does not receive the appropriate level. Local budgets are formed on the principle of minimum execution. However, the local taxation system development and the significant increase in tax revenues from local taxes since 2015 allow us to make optimistic forecasts for the growth of the financial self-sufficiency level for local budgets in the future. Keywords: self-sufficiency, community, budget, taxes.
