In the paper is described a new computerized test bench for strength testing of roll over protective structures (ROPS) in tractor cabs. The static test procedure complies with international labor safety standards accepted in the Republic of Belarus.
In the paper is discussed an energy saving effect of implementation at pig-breeding farms the automatic system of distribution the liquid feeds multi-times per day. There is given a mathematical description of the intellectual functions of the operator transferred to the PLC program of the control system. There is quantitatively estimated an energy saving effect of distribution the liquid feeds multi-times per day compared to twice per day.
This paper looks at the question of reducing power consumption and improving energy efficiency in the technological process of distribution liquid feeds in a pigsty. There is suggested a way of saving energy by optimizing the power of electrical motor of centrifugal pump supplying the feed into the piepline. The energy saving effect is estimated and reducing power up to 10% is shown.
