Enhancement of Efficiency of Electro-Optical Systems by Means of Optimization of Spring-Loading of EOS Actuators

AbstractTo eliminate pitch-play in the interacting teeth of gears of EOS actuators, the gears are spring-loaded. This paper shows that traditional EOS actuators have, by an order of magnitude, a greater wear-and-tear and weight of the actuators, overheating, etc. The approach suggested hereby enables optimization of gear spring-loading and considerably improve the efficiency of EOS

Analysis of the Efficiency of the Multipair Toothing Application in Reduction Gearboxes of EOS Actuators

Conventionally, a one-pair toothing is used in reduction gearboxes of EOS actuators. A spring-load is applied to the teeth for the elimination of backlashes, which causes premature wear, increased power consumption, increased weight of EOS PA (platform actuators), etc. This study shows that the multipair toothing application allows to solve these and other problems. © 2016 The Authors

The detection of flaws in optoelectronic systems

Potentially dangerous spots (PDSs), for example, leaks in product pipelines (oil and gas pipelines), are revealed using optoelectronic systems (OESs) that are usually mounted on airborne vehicles (e.g., helicopters). Earlier, a relevant problem consisted of revealing the onset of leaks in PDSs; however, today it is necessary to detect the PDSs of leaks in order to prevent their development. The complexity of the problem is related to the fact that product pipelines are most often located near densely populated areas and near reservoirs with drinking water. The appearance of PDSs is usually characterized by deviations in the temperature and other physical parameters from standard values in small areas. The detection of such spots necessitates decreasing the flying height of an OES carrier. As a rule, this yields a deterioration of imaging quality and OES overheating, which decreases the effi- ciency of this PDS detection method. Conservative OES developers believe that a low imaging quality and OES overheating result from random flaws in the OES assembly. Contrary to this, it is shown that failures occur due to a deterministic flaw at the stage of designing drives for an OES platform. © Pleiades Publishing, Ltd., 2012

The development of a high-precision environmentally friendly method for measuring the thickness of rolled sheets

A triangulation method for measuring the thickness of flaws with the guided radiation of a sounding signal and its reflection from the surface of a rolled sheet and reception in transducer's elements, which correspond to the measured thickness and other parameters of a rolled sheet, is considered. The high density of dust in the atmosphere of rolling mill stands and the thermal radiation of a heated rolled sheet are shown to be the principal disturbances in the measurement of such flaws by this method. For this reason, the spectral wavelengths adjacent to the IR imaging wavelength range, viz., thermovision and microwaves, are used in this triangulation method. The advantages and disadvantages of both existing and our coordinate measurement methods are demonstrated by the example of measuring the thickness of a metal sheet. © Pleiades Publishing, Ltd., 2012
