The article presents the relevance of the topic associated with the introduction of technical diagnostics tools and the service system of electronic equipment for AC electric locomotives. Results of operating a microprocessor control system and diagnostics of AC electric locomotives on the Eastern operational area are presented in the form of failure statistics of elements of microprocessor technology. Structure of the technological process of servicing AC electric locomotives on the railways of the Eastern operational area is shown. Authors revealed features of building a system of locomotive maintenance points (LMP), which carry out repair and maintenance of electronic equipment for AC electric locomotives of various series. Functional scheme of the system for servicing electronic equipment for AC electric locomotives has been developed. Bench and technological equipment of the service area for the maintenance of electronic equipment is shown. The article describes development of an automated workplace (AWP) for optimization and repair of a microprocessor control system (MCS) for an electric locomotive, which was not previously in the locomotive sector. Examples of performing technological processes of repairing cassettes of MCS using AWP are given. The following conclusions were made: 1. Statistics of MCS failures and malfunctions of their cells on AC electric locomotives at the Eastern operational area for the period from 2016 to 2018 (LMP of station Tayshet and Karymskaya) shows that the number of failures of MCS decreased by 30 % and the number of malfunctioning MCS cells, received for repair, decreased by 45 %. 2. Automated workplaces created in the JSC “DTsV of the Krasnoyarskaya Railway” for optimizing and repairing the local government of AC electric locomotive made it possible to optimize repairs and create an automated process for the maintenance and repair of electronic equipment for electric locomotives. 3. Developed by specialists of the JSC “DTsV of the Krasnoyarskaya Railway” together with the employees of the LLC “Lokotech-Service” technological model of full service maintenance and repair of electronic equipment for AC electric locomotives on the railways of the Eastern operational area was implemented and well proved itself in the work of the LMP.

Long Stroke

For ultraprecision machine tool of the next generation, two novel positioning devices are invented by the authors. The first positioning device of nanometer and sub-nanometer resolution with long stroke is the Twist-roller Friction Drive (TFD). For long stroke with 1nm of positioning resolution, the TFD is driven by a servomotor, and it is driven by a piezoelectric actuator for short stroke with 0.1nm of positioning resolution. The second positioning device of short stroke picometer resolution is an active aerostatic guideway employing the Active Inherent Restrictor (AIR). The stroke of the active aerostatic guideway is in the order of 0.1μm, however, the positioning resolution can be 50pm. These positioning devices are integrated into a tri-mode positioning system and each positioning mode is controlled by a numerical control system.
