  • Multiparameter sensor pnevmomehanichesy position pneumatic actuators

    In the article the automatic drive positioner technology systems increased speed and accuracy on the basis of multi-parameter sensor rotor (MPMD). The proposed scheme, technical solution (MPMD) with improved integral evaluation of several parameters of positional displacement control objects. The generalized mathematical model of the sensor actuator position struktre. Computational experiments by the Runge-Kutta in the environment of the program Matlab-simulink are obtained depending on the basic parameters of an actuator position. When you perform a typical positional cycle The influence of the major geometric, hydraulic and thermodynamic characteristics of the expiry of the compressed air through the nozzle sensor element on its expenditure-Perepadnaya response. It is found that the maximum deviation does not exceed 5% of the reference sensor. This will improve the accuracy of parameter estimation process of positioning and formation of control actions in real space and time.

  • Formation of array nanoparticles during electrodeposition platinum on glassy carbon and dispersed carbon support

    In the present study, platinum was electrodeposited onto rotating disc electrode coated with Vulcan XC-72R Nafion suspension and uncoated smooth glassy carbon electrode from acidic solution of 5mМ H2PtCl6. The electrochemically active surface area of platinum particles obtained was determined by cyclic voltammetry and the structural characteristic of the particles was studied by scanning electron microscopy. The impact of current and time on the electrochemically active surface area of platinum particles electrodeposited on the carbon supports was also investigated and described in this paper. The present work is expected to be utilized and contribute to the improvement of electrochemically active surface area of platinum catalysts for low temperature fuel cells.

  • The radiation exposure estimation on biological tissue under gamma irradiation

    The paper presents the results of computational statistical experiment to estimate field radiation exposure on the soft tissue of the human body when external pressures are nondivergent narrow beam of gamma photon radiation. As an example, adopted the energy of a photon that enters 102 group energy axis constant laboratory ABBN. Given dose distribution in a cylinder diameter of 20 and a length of 10 centimeters. The method of statistical tests, known as Monte Carlo. Is used modify of the method with calculation the inverse functions. It is shown that the dose outside the beam ionization radiation load decreases by two orders, remains finite, that should be considered in therapeutic procedures, in which the total dose exceeds the lethal dose for a healthy bod

  • Finite element analysis of the applicability of the applied theories of calculation of piezoelectric device of energy storage of stack configuration

    This paper considers basic element of device of energy storage which is a piezoelectric generator (PEG) of cylindrical form with the attached inertial mass. A finite element modeling of the device operation is carried out during active load in the external circuit. The main purpose of the operation is to compare the output potential and frequency characteristics of the device known in the literature models of systems with concentrated parameters. On the basis of these models, we can receive the analytical dependence of parameters of PEG with its geometric characteristics and mechanical properties of the used materials. However, the question of the range of applicability of these formulas is still open. In this paper, based on the numerical analysis of finite element models of PEG in package ANSYS, we obtained comparison with the analytical formulas that show the values of some parameters of simplified models and set the boundaries of their applicability.
