The authors proposed a simplified segment-model of spherical aerostatic bearings which allows to determine static and dynamic behaviour of bearings. The model is based on two physical assumptions: the number of estimated segments is considered large, and the speed of tangential bearing surfaces is considered negligibly small. Bearing reactions are estimated on the basis of a series of preliminary calculations of air pressure in a separate segment field. The pressure field estimation is performed with the finite-element method in MATLAB program in a nonlinear formulation. The proposed model was tested on spherical aerostatic bearings with porous boost limiters developed for the high-precision nonferrous metal-turning work spindle. The segments number influence on accuracy of load characteristics is estimated.

Problem of evaluation of the zone of dangerous trajectories in the case of dynamic circle forbidden zone is considered on the basis of the obtained description. As a result iteration algorithm of the zone of dangerous trajectories evaluation is formed.

Existence of oscillatory mechanism of solidification of metal welded bath in the form of recurrent formation isotherms of crystallization is characteristic for different metals and alloys. It was found that under the influence of heat from an external periodically active source with the frequency corresponding to natural frequency of crystallization of weld material, resonance conditions which contribute to crushing the cast structure of seam and heat-affected zone are created. Fine structure of the welded joint obtained by effective control of the oscillatory mechanism of the crystallization front, can significantly improve hot cracking resistance and, probably, cold cracking due to changes in conditions of structural transformations, unachievable by conventional welding. Frequency of external action which creates conditions for parametric resonance can have several meanings according to the theory of oscillations.

The process of metal melt during welding with subsequent crystallization is characterized by several features. Transition of liquid melt to solid state occurs simultaneously at the interface in the so-called germ band. It is in the embryonic area that during crystallization there appears an oscillatory mechanism which is considered within the framework of a phenomenological model. Modeling the dynamics of particle motion in simple liquids confirms transition from the chaotic state of the particles into the ordered one with preliminary formation of clusters of several particles. The mechanism of layer-wise phased transition of the particles occurs at establishing a specific frequency and mode of unstable equilibrium or breakdown. Using an external source of fluctuations synchronous with the process of crystallization rate, you can control the formation of the structure by creating a resonance condition. This would be a significant improvement in the properties of welded joints by grinding the cast structure of the weld metal.

Now in the Russian army and in the national economy of Russia a considerable quantity of cars with number of axes four and more is used. Operating experience of these cars showed that the problem of increase of mobility of these cars at the expense of decrease vibration crew and transported cargo was urgent. One of directions of improvement of the given property is management of damping in a suspension bracket by compulsory change of factor of damping. Developed algorithm of management of two-level damping of a suspension bracket multi-wheeled vehicles allows to decrease essentially the level of fluctuations of the case of the cars and to raise their speed on dirt roads. The algorithm is simple in implementation, provides fast reaction of suspension system on changing road conditions and doesn't demand high-speed executive powers of a suspension bracket that positively affects their durability. On the basis of the analysis of the results of modeling for various traffic conditions of the car with the wheel formula 8x8 the conclusion about the efficiency of the developed algorithm was made.

It was shown that the mathematical model described the processes, proceeding in a design two-volume PHS, precisely enough.

The authors give a detailed description of car electromechanical transmission control at the individual distribution of power in the wheels, the main essence of which is proportional to the relative distribution of the normal load to be carried by the wheel. The law is adapted for two versions of drive control: "angular velocity" and "torque". Effectiveness of the law is proved by the results of mathematical simulation of car motion with 8×8 wheel formula on the basis of non-deformable reference to two cases: upgrading (with “angular velocity” control) and curvilinear motion with a fixed radius (with “torque” control). The directions of future research is the need to study car movement with the proposed transmission control in a wide range of external influences ("mixed doubles" motion, acceleration, motion on a deformable substructure, etc.), and also in comparison with the results of movement with traditional transmission patterns.
