The new real representations a component of stress tensor and deformation tensor are received through the three-dimensional harmonious and biharmonic functions forming stress function tensor. The found expressions allow to reduce the basic boundary problems of the spatial theory of elasticity to boundary problems for the biharmonic equation.

The collision problem in the technological equipment with two and more planar positioners on the same stator is described. A geometric interpretation of problem is given, and the algorithm for analysis and excepting of collisions is proposed. The multimedia page for the modelling of two planar positioners' motions on the same stator is presented.

For researching the movement of flywheel vehicles the physical model is proposed. Physical model as well as real car has a flywheel engine which rotates with high speed. In the article the main parameters of such model and flywheel engine are calculated. It is shown that the engine of the model has parameters which can easily be achieved while constructing.

These presented the particular features of developed software for organization all types of training work in the course «The theory of mechanisms and machines» - training, control of the knowledge, laboratory works, course designing.

The article deals with some peculiarities of teaching calculating engineering task solutions to students on the bases of Mathcad.

Various aspects of application of the differential equation for the description of character of movement of work part in the device for pneumocentrifugal processing are described.

The correlation analysis of weight values of direction vectors and their order numbers of normalized vector model for objects under investigation is proposed. The experimental results of construction of the regression line are represented, as well as ones for calculation of theoretical-correlation ratio, similarity measure and classification of objects under investigation for a ...

The main limitation of assembly of the connections formed by mechanic pressing-in are noted, the new engineering solution on hydropress disassembly connections is described, the basic theoretical relations of process of a hydrothrust in a part jointing with guaranteed interference are adduced.

h was developed computer model of single graphite atomic layer (graphene) crystal lattice on basis of valence-force-field approach. One performed computational experiments to determine mechanical cluiracteristics (linear elasticity modulus, crosscut compression coefficient, shear modulus) according to graphene particles dimensions. One realized comparison present results with ...
