  • The design's technique of combined drills with replaceable multiface plates

    The technique of the geometrical analysis and the analysis of force loading of combined drills with the replaceable multiface plates is offered in this work. This technique is allowing to determine geometrical parameters and specific force loadings in each point of a plate’s cutting edge taking into account its orientation in the drill case. Application of this technique allowed to establish the reasons of the drill’s low durability. The offered technique allows to design drills from the minimum unbalanced radial component of cutting force which increases its working capacity and the processed holes quality. New designs of combined drills both with two, and with three replaceable multiface plates are offered in this work. The durability of this new drills is increased by the plates mutual turn for the minimization of an unbalanced radial component of cutting force

  • Influence of specific pressure of pressing and firing temperature on frost resistance of the modified laboratory samples from atyukhtinsky clay raw materials

    Results of researches on joint influence of specific pressure of pressing and firing temperature on physico-mechanical properties of laboratory samples on the basis of atyukhtinsky clay raw materials is shown. For the purpose of increase of frost resistance of the burned samples into structure of masses entered a carbonat containing modifying additive in an amount of 5%. For a quantitative assessment of influence of the specified factors on the main indicators of the burned samples researches with application of mathematical planning of experiment and computer processing of results were conducted. Specific pressure of pressing varied within 20±5 MPa, firing temperature – 1000±50 0C. By results of experiment the regression equations are received. It is defined that at increase of value of both varied factors, frost resistance and durability of samples increase, and water absorption – decreases. It is shown that, operating even with two technology factors – the specific pressure of pressing and firing temperature – it is possible to change significantly properties of finished products, and, using the received equations, it is possible to predict future properties of products at a stage of their production.

  • Research of the influence of the development level of intelligent transport network on the efficiency of intermittent bus lane priority application

    The article deals with the analysis of intermittent lanes priority based on simulation. The implementation of intermittent lanes priority system is only possible within the framework of urban intelligent transportation system (ITS).  In some cases, there are not always enough ITS components for the operation of intermittent lanes priority system. Based on the simulation it is possible to determine the efficiency of the intermittent lanes priority system with the minimum or complete number ITS components. To compare the effectiveness of intermittent lanes priority system the simulation was performed for the four scenarios:
    1. Without the use of public transport priority
    2.  Classically  marked priority lane
    3. Using the intermittent lanes priority system with a minimum number of ITS components
    4. Using the intermittent lanes priority system with the full amount of ITS components 
    According the results of simulation we concluded that the minimal intermittent lanes priority system is noticeably inferior to a fully functional intermittent lanes priority system on the effectiveness, but such system does not require a high level of development of the urban ITS and can be considered as the first stage of a complete intermittent lanes priority system.

  • Flexible piezocomposites with mixed connectivity phases in the system

      Laboratory technology was developed to fabricate flexible piezocomposites with ferroelectric phase - polymers having signal reception factorv • gv 5000 • 10-15 m2 / N. The values of the given coefficient were achieved by switching from a probabilistic (spontaneous) percolation to a correlated one in the process of forming material. This made the production of 0-1–3 piezocomposites, in which a part of piezophase has 0 connectivity, and the other part – 1 connectivity possible. To improve the efficiency of piezocomposite polarization before their manufacturing the surface of piezophase particles, which were obtained by the partial destruction of the porous frameworks, was treated with coupling agent, which did not only improve the polymer adhesion to piezophase, but also allowed the removal of water from the particle surface. The latter effect reduced the value of interfacial conductivity, i.e. prevented the voltage drop of the polarizing field. Matching of polymer conductivity and piezoceramic particles by determining the optimal polarization temperature was carried out as well.
