  • A numerical analysis of the stability of the shallow spherical shell reinforced with ribs along the contour, using varitional-difference method

    The article contains an analysis of the shallow elastic spherical shell on a rectangular plan, reinforced with ribs along its contour, under the uniformly distributed load. The problem is solved numerically with the variational-difference method, considering the geometric nonlineaity and the shear deformations of the shell and the ribs. As a result, the dependencies of the critical load on the shell stiffness and the ribs stiffness are obtained.

    Keywords: shallow spherical shell, ribbed shell, stability, bending stiffness, geometrical nonlinearity, variational-difference method, critical load

  • Development of a methodology for the formation of an estimate for a construction object based on its information model

    The development of a methodology for the formation of an estimate of a construction object on the basis of its information model is considered, taking into account the state of development of software systems for BIM modeling and the peculiarities of regulatory regulation of the construction of construction projects in Russia.

  • Simulation model in the circuit of management of organizational conflicts

    Organizational conflicts are a natural and integral part of any process. In modern control theory, it is proposed to use various adaptive control structures to solve such problems, in particular, with reference or configurable models in the control loop. A cognitive model of adaptive management of organizational conflicts with a configurable model in the management loop is considered. Embedding the model in the control loop allows you to integrate information about the dynamics of process characteristics. Based on information processing, a variant of controls for de-escalation of the conflict is proposed. The model in the organizational conflict management loop is essentially an intelligent conflict situation analyzer. It presents options based on the accumulated and processed information within the framework of known precedents for their solution. The core of such analyzers is a simulation model based on the system dynamics paradigm. The built simulation model allows you to evaluate and predict the impact of factors, ways to stabilize and manage organizational conflicts, taking into account the main parameters. In accordance with the concept of adaptive management, the model can be configured for the current values of the conflict situation parameters and, in accordance with the already tested options, can offer management in a specific situation. The use of the system dynamics paradigm in the model for building an effective forecast is focused on the strategic level of management.

  • Simulation modeling of individual's activity in the context of organizational conflicts

    This scientific study presents an analysis of organizational conflicts, as well as problematic aspects of activity in contemporary realities. The effect of organizational conflict on the effectiveness of an individual is shown. The urgency of researching the problem of the activities of the organization’s employees in the context of organizational conflicts, as well as ways to solve them, is given The analysis of the cognitive model. As factors used to reduce tensions in a team, it was proposed to introduce factors for raising qualifications and organizational culture. These factors will influence the target factor - performance. In the course of simulation modeling, it was found that by carrying out activities to improve the skills of employees, measures to increase the level of organizational culture of employees, the organization seeks to reduce tension in the team and, as a result, there is less staff turnover.

  • Development of metal-ceramic composite material for the friction unit of the absorbing apparatus of the railway car

    The absorbing apparatus serves to extinguish the impact when the wagons cohere and move. Most of the energy, about 80%, in this system is absorbed by a friction unit consisting of a friction wedge and a fixed plate. Absorption of energy in this system occurs due to the work of frictional forces arising during longitudinal motion of the pressure wedge with respect to the friction plate. Due to the large shock-frictional loads, intensive wear and destruction of the cermet cake occurs, which adversely affects the energy capacity of the absorbing apparatus. To eliminate these shortcomings, studies were conducted to create a new material. After numerous experiments, a composition was obtained with the optimum content of components, which maximally satisfies the working conditions of the friction unit and the requirements imposed on these devices.

    Keywords: absorbing apparatus, friction unit, cermet, wear resistance, friction plate, powder material, sintering technology

  • The theory of the dynamic pressure arising in the top suspension bracket balloon cable system.

    In clause the opportunity of use balloon cable system descent to transport operations in remote mountain conditions is described. Dependence of system on wind influences is reflected. Proceeding from this, the design procedure of dynamic pressure which arise in the top suspension bracket of system is resulted, in view of mobility of a balloon under action of a wind. The technique allows to estimate the pressure arising in the top and bottom points of a suspension bracket at change of force of a wind, lengths of a suspension bracket, a corner and speed deviation of a balloon.
