In most practical cases, rotor systems are complicated mechanical objects. In solving a number of problems, such as investigated of dynamics and determining the technical state of elements of a rotor system, it is necessary to measure the spectral characteristics of vibration of some connection joints. As a rule, this is not always possible to do directly and leads to the need for a structural analysis of vibration processes. This analysis includes some questions such as partitioning complicated mechanical system on elementary systems, estimating relationships of coordinates and determination of unobservable parameters by observable. The graph method of connections is one of the most promising techniques of structural analysis. This method determines typical models of the dynamic processes of rotor systems with regard to characteristics of individual elements.
The overview describes the main directions and results of the II International Conference “ICMSIT-II-2021” held in St. Petersburg in March 3-6, 2021. It gives the details about the participants and the proceedings. The anchor partner of Krasnoyarsk Science and Technology City Hall was St. Petersburg State University of Aerospace Instrumentation. A description of the main trends in modern innovative technologies, engineering and industrial physics as well as in the development of the third International Forum “Metrological Support of Innovative Technologies” by the St. Petersburg State University of Aerospace Instrumentation is given in the overview.
In the context of the digital transformation of the economy, the effective development of corporate information systems of research and production holdings of aerospace instrumentation is becoming one of the decisive factors in ensuring the high quality of domestic avionics. This article is devoted to the analysis of the influence factor of digitalization and informatization processes in scienceintensive industries of modern aerospace instrumentation, as well as the definition of a qualimetric model for assessing its impact on the quality of domestic avionics products in the current economic and technological conditions. The influence of the level of development of corporate information systems of aerospace instrumentation enterprises on the quality of domestic avionics products is assessed in the article on the basis of the corresponding hierarchy of quality indicators. The proposed model of the influence of the level of development of corporate information systems on the quality of aerospace instrumentation products assumes the choice of the form of the integral criterion depending on the external requirements for the efficiency of the assessment, the sensitivity of the system of quality indicators.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
