In this article we have identified analytical dependences of position of an automatic control system output coordinate for optimum speed diagrams for small movements of actuating device of electric drive and its moving error value
In this article we have developed the optimum speed diagrams for small movements of electric drive’s actuating device. We have identified analytical dependences of position of automatic regulation of system control signal of time, which allows to form the optimum speed diagrams for small movements of electric drive’s actuating device with ultra-precision
In this article we have investigated fatty acid composition of oil made of flex seeds of VNIIMK-630 traditional variety and new selected SURPRISE variety. The comparative analysis of composition and factional composition of tocopherol in oil made of these seed varieties has been carried out. We studied changes in acid and peroxidation numbers when flex seeds are stored in the dry condition
The optimal angles of spatial orientation of disk tools are found basing on the mathematical model of the universal soil-processing instrument. The optimization problem has solved basing on analytical approximation of imitational modeling results and optimization map analysis
The problem of calculation of arguments of the controlled cascade electric drive is reviewed. For a basis the electric drive is taken by the designed writers. For definition of the moments the method grounded on electromechanical transforming of energy is proposed.
On an example of a present construction the values of currents of a stator and rotor and phase angles of these currents were retrieved. It has allowed to find the energy, accumulated by the device, in the given instant. Utilizing this result, the instantaneous moment was defined. The introduced mathematical model realized as the program in environment Delphi. Inaccuracy for an audit example did not exceed 10-15 %
In the article we have presented the results of research of influence of activated mineral fillers on mechanical properties of fine-grained concrete. It is shown that clay and zeolites in mechanical activated condition have increased both early and estimated durability of concrete
