The processes are considered when the stages of weakening TED magnetic field switched on diesel locomotives TE10 type. analysis unstable operation and automatic switching transition relay at partial loads corresponding to locomotive's speed rated load in is carried out. current algorithms proposed for correcting scheme transitions from a full weakened field. A variant correction circuit check i...

The Center for Electromechanics has developed and is currently testing a 2 MW, 130 kWh (480 MJ) flywheel energy storage system (FESS) designed as a load leveling energy management device. The flywheel energy storage system consists of the energy storage flywheel, a high speed induction motor/generator, and a bidirectional power converter. The FESS is a key element of the Advanced Locomotive Pro...

The article presents the problem of substantiating fuel and energy efficiency use diesel-powered mainline locomotives on a real, hilly-mountainous section Uzbek railway. is solved using methods theory locomotive traction for various conditions organizing operational activities three-section freight diesel UzTE16M3 when driving trains different mass. main research criteria are kinematic paramete...

Equipment with diesel engines is used in all mining enterprises. Monorail transport of great importance coal mines, as it facilitates the heavy labor workers when transporting materials and people, fixing workings, refueling repairing equipment, which leads to an increase speed tunneling operations. Reducing concentration harmful gases from diesel-hydraulic locomotives at workplaces mine locomo...

Transportation noise contains significant low frequency components. It is difficult to sound insulate buildings against transportation noise because wall cavities are only effective in increasing sound insulation above the mass-air-mass resonance frequency. Stud walls can also have a significant structural resonance in this low frequency range, although it is not yet clear if this is significan...

This article presents a mathematical model of the risk failures, depending on operating parameters, locomotive diesel engines. The purpose this study is to determine failures engines in maintenance. theory probability and logic reliability are used theoretical study. innovations main works first approaches calculating by hourly fuel consumption, which, under operational conditions, allows for e...

Purpose: Efficiency increase of operational monitoring technical state gas-air tract (GAT) a locomotive diesel, assessment possibility using regular measuring tools to monitor diesel GAT state; feasibility justification for expanding the list parameters that are monitored by board diagnostics. Methods: An intelligent classifier based on Support Vector Machine (SVM) algorithm is used determine c...

The results of strength and gas dynamic improvement of turbocharger TK-32 axial turbine are presented. Turbocharger was manufactured by LLC “Penzadieselmash” (Penza, Russian) and is used as unit boost for diesel locomotive. The goal of this work was to ensure turbine work capacity when rotor speed is increased by 10% without efficiency reduction. The strain-stress state analysis indicated the r...
