Dynamic stresses, which arise in drive and traction element during operation of the conveyor have been investigated on the basis of the developed mathematical model. Calculation has been conducted with regard to its elastic and dissipative properties. The analysis of the obtained results has been carried out, with and without taking into consideration dissipative properties of the conveyor's element.
Numerical calculations of mechanical system behavior at pulsing feeding into of energy in the test specimen from plastic materials are carried out. Essential nonlinearity of pulse transfer process on the test specimen that specifies in possibility of jump transitions in material structural condition at minor alterations in entry conditions is revealed.
In the given research the solution of problem of optimisation of regime of acceleration of one-mass dynamic system is resulted. Optimisation is carried out by means of variational calculus methods. For the account of limitations superimposed on regime of driving of system the Lagrangian multiplier method is used. The analysis of agency of magnitude of factor of Lagrange on parametres of driving of...
There are the aspects of providing reliability of elements of agricultural machines are considered structurally-technological methods during realization of control of their application computer holography in paper. Examples of holograms, which show on possibilities realization of non-destructive control holography are made.
The ways of development of industry of the pig breeding are analysed and the row of basic principles the observance of which at planning provides the maximally effective production of pork is certain.
There are presented methods of forming of logically-probabilistic models of reliability of difficult structural systems in the article. The criteria of minimization of short cuts and minimum sections are offered for increase of reliability of facilities for preparation and distribution of forage.
