Application of the Taylor test (cylinder) allowed to obtain experimental data on dynamic behavior of volume-perforated samples of the aluminum alloy D16T at an impact velocity against a hard wall of up to 150 m/s. To calculate the impact, software packages LS-DYNA and ANSYS AUTODIN in two versions were used. The first variant included direct modeling of the structure of volume-perforated samples by the finite element method, and the second variant included using constitutive equations of porous elastoplastic medium based on a homogeneous model. For the second calculation variant the authors applied both experimental data in the form of a deformation curve obtained for uniaxial stress state and calculation data based on numerical simulation of deformation and compression of volume-perforated samples. The authors received a good qualitative agreement between the calculated and experimental data in the Taylor test, as well as a satisfactory quantitative agreement between the calculated and experimental results.

 In order to move objects with submicron accuracy and vibration control of equipment, in modern precision equipment precision positioning mechanisms based on magnetorheological fluids (MRF) can be successfully applied. It is shown that the work of these mechanisms have a significant impact on the properties of the fluid and, in particular, on electrical resistance and the bulk modulus of elasticity. It was found that with application of an external field to MRF electrical resistance decreases by 30% and the bulk modulus increases by 18%.

# 09, September 2012
DOI: 10.7463/0912.0453646
A.A. Yakomaskin
Development of loop heat pipes (LHP) is connected with their miniaturization. To reduce thickness of the CTT it is necessary to optimize the evaporation zone. For this purpose, a pilot evaporator open to the atmosphere was created; it consists of a microchannel plate with intercostal length of 300 micrometers, a wick and a compensation chamber. The area of the heat supplier is 19x19 mm. Water is a heat carrier. The experiments provided data on temperature distribution along the height of the wick, on temperature in the compensation chamber and on temperature of a microchannel plate surface. These data offer opportunities to further optimize the evaporation zone, which will create thinner evaporators.

Modeling of zero signal compensation processes in MEMS gyroscope
# 09, September 2012
DOI: 10.7463/0912.0476265
S.F. Konovalov, V.P. Podchezercev, Yu.A. Ponomarev
One of the most important characteristics of micromechanical gyroscopes is zero-signal value. Studies have shown that pattern shift to 1 micron (achievable accuracy of double-sided photolithography) results in appearance of zero signal corresponding to angular velocity of TLS which exceeds the measurement range. The main sources of this signal are: pendulum asymmetry and technological inaccuracy during manufacturing the SE elastic suspension. Influence of pendulum asymmetry on the zero-signal value can be minimized by design and technological measures. This article presents the results of investigations into the possibility of compensation of manufacturing defects of elastic suspension which are due to a shift of etching photomasks with double-sided photolithography used in manufacturing suspensions.

# 09, September 2012
DOI: 10.7463/0912.0453605
D.N. Karbyshev, V.I. Hvesyuk
The experiment showed effects of growth and destruction of drift waves which are directly responsible for plasma turbulence. As at the linear approximation of such waves the oscillation amplitude in the plasma is assumed to be small; it is impossible to to assess its value. The paper takes into account the amplitude finiteness of the drift wave and considers qualitatively the drift wave instability dynamics at nonlinear approximation. On the basis of this analysis it is shown that the presence of a linear velocity profile leads to wave breaking and suppression of turbulence. The authors obtained different characteristics depending on the nonlinear factor, increment of growth, wavelength, and initial amplitude.
