Abstract

The advantages of autogenerator displacement transducers in track control systems of metal - cutting machines, industrial robots, robotic complexes and flexible automated productions, such as high speed and durability of control systems, as well as their disadvantages the lack of sufficiently complete accuracy characteristics, which affects the efficiency of equipment with track control systems, are considered. Formulated the research problem and described a special experimental setup, which studied the sensitivity of the self displacement transducers three types based on their mutual arrangement and screens of various metals (iron, steel 45, steel St3, 12KH18N10T steel, brass, dural and copper), as well as the conditions of their operation depending on the positioning of screens. The results of experimental data processing are presented, and any dependence of sensitivity on the screen material is not established. The assumption about the randomness and insignificance of the revealed differences is put forward and verified, and it is shown by the Cochran criterion that they are rightfully considered insignificant with a reliability of at least 95 %. The influence of power supply voltage fluctuations in the network on the accuracy characteristics of auto generator displacement converters is studied and the results of the research are presented. A statistical test was carried out using the student’s criterion, which showed the absence of this influence on the accuracy characteristics. It is noted that hysteresis occurs during the operation of autogenerator displacement transducers and it is experimentally established that in most cases it increases with the transition from a diamagnetic screen to a ferromagnetic one. It is proposed to use the results of the research of precision characteristics in the design and efficient operation of the system limit control on the basis of self converters of displacements of the considered types, addressing issues about the need to use the voltage regulator when selecting screen material, etc.
