Analysis of the influence on the structural composition of the soil of the main design and regime parameters of the vibratory roller

The article presents the results of experimental studies of a soilcultivating vibratory roller, as a result of which adequate mathematical models have been obtained that characterize the rolling process from the standpoint of compliance with the reference values of the structural composition of the soil. From the condition of ensuring the best quality of work, the optimal mass of the vibratory roller and the rotational speed of unbalancers are determined. According to the results of the research, it was revealed that the quality of rolling by the developed vibratory roller, estimated by the coefficient of compliance with the standard, is 29.9% better than that of the KKZ-6 roller commercially produced by the industry

Field studies of the wave roller

The article presents a description of a fundamentally new design of a soil-cultivating wave roller and presents the results of its research. Adequate mathematical models of the soil rolling process are presented from the standpoint of compliance with the reference values of its density and aggregate composition. Thanks to the research, it was found that the quality of rolling by the developed wave roller is 20.9% better than that of the KKZ-6 roller commercially produced by the industry. To obtain the most high-quality rolling result, the developed wave roller determined its main design and operating parameters optimized for the process of surface tillage, namely: the speed of movement and the distance from the edge of the hollow cylinder to the inner surface of the compactor

Development and concentration efficiency study of enterprises innovation activity in real sector of economy

The relevance of the issue under investigation is reasoned by the fact that in growing global competition and expansion context, on the one hand, and economic constraints related to geopolitical tensions, on the other hand, a key factor in the enterprises competitiveness and priority positions achievement in the world market will be their transition to innovative production technologies and business. Topical and promising one in this case is to achieve competitive excellence, increase business efficiency through the innovations' projecting and commercialization. The paper purpose is to investigate the efficiency and specificity level of the ongoing innovation processes in the real sector of the economy as innovative transformations key segment and the basis for increasing the territory competitiveness. The leading method to the problem study is the method of systemic economic analysis, which allows revealing the essence, regularities, trends of the processes occurring at all levels of innovative transformations. To assess the innovative activity concentration and enterprises' innovative development nature, it is proposed to use analysis methods based on the cost efficiency evaluation, depending on the effect magnitude achieved as a result of innovations practical use, enabling to diagnose competitive and non-competitive producing groups, to determine the resource and innovation potential with strategy development further construction. The research materials can be used in innovative transformations management in organizations of the real sector of the economy, economic regional systems formation, the territories competitiveness management and innovative development's strategies construction. © 2017, Authors
