For а cam mechanism with а shaking rocker actuator the problem of its dynamic synthesis with use of information technology CAD system Компас-ЗО V12 is shown. Problems of calculation of the law of movement of a rocker actuator, definition of basic dimensions, construction centre and a working cam profile, construction of the schedule of a corner of pressure are consistently solved. ...

The article phenomena, soft modes and negative Poisson’ ratio are considered on bases at statistical theory.

This article contains а description of a new method of unevenness definition in dependence of obliquity angle and its influence on output cinematic characteristics of two-joint cardan shafts. Also conducted a study of cardan shafts using correlation-regression analysis.

The account of torsion bars with a non-round cross-section is presented. It’s a practical interesting method as most simply account. The approximation of geometrical reinforce with 8 per. miscalculation is received. The particular cases of non-round cross-sections (there are ellipse, triangle and rectangle) are considered.

The rules of designing for irregular thickness coating devices are subscribed. Irregular thickness coatings have be obtained by irregular part angular velocity accordingly wear value, which is measured in every point of part surface.

В работе приводятся результаты теоретических исследований падения тяжелого тела в воздухе при квадратичном законе сопротивления. Получен ряд аналитических зависимостей, характеризующих основные параметры этого движения.

Nanomaterials is а field which takes a materials science-based approach to nanotechnology. It studies materials with morphological features on the nanoscale, and especially those which have special properties stemming from their nanoscale dimensions. Nanoscale is usually defined as smaller than a one tenth of a micrometer in at least one dimension, though this term is sometimes ...

То investigate by means of engineering package ANSYS the VAT matrix stenta, implanted into a blood vessel.

It is carried out the mathematical simulation of creep of the three-layered cylindrical shells, reinforced by the fibers of a constant cross section. It is investigated creep of the shells with the unequal strong and equal strong stressed reinforcement, loaded, in the general case, with transverse pressure and axial forces. Solution of the problem about creep of shells under the ...

For flat mechanisms with the higher steams (gear, cam and similar) classification with allocation of groups with w=0, containing the higher steams is offered. In most cases such groups are one-links (with n=l, P„=l, Pb=1), and two-links (c n=3, Pi=2, Ph=2).
