    Evaluation efficiency of diesel-generator sets according to the control parameters results during the rheostat tests

    Abstact. During automated rheostat tests of locomotives itʹs necessary to control a lot of parameters of the diesel generator set and support systems. Due to the features of perception of the information by human the control is brought to the observation of a small number of parameters. Implementation in practice of rheostat tests of automated systems of inspection and testing allowed to expand the amount of received information. In this article is offered using automated control systems of diesel-generator sets parameters during rheostat tests which allow to accumulate and analyze test date using developed protocols forms and pivot tables with parameters in entire range of loads, also it helps to determine the quantitative index of a technical condition of diesel-generator set.

    Calculation of distribution load between rolling bodiesin the roller bearing of the traction motor

    The article proposes a method of calculation the load between the rolling bodies of the swinging bearings and the bearings of the traction motor, which makes it possible to have the value of the radial clearance in the bearing, as well as the radial movement of the inner rings relative to the outer one. To determine the load perceived by the most loaded rollers, a solution of the equilibrium equation for internal elements is proposed using simple iterations. The implementation of the method is implemented in the Matlab software package. Using the proposed method, the load distribution between the rollers in the traction motor of the VL11K electric locomotive was calculated. To determine the load acting on the bearing, the “Sarga-Subic” section was selected, which has a mountain profile.

    Rationale the possibility of electric train energy consumption decreaseat west siberian railway omsk department

    In article the possibilities of decrease in energy consumption on draft at the movement of electric trains in the conditions of a flat profile of West Siberian Railway due to shutdown of traction section of an electric train and rational distribution of time of the course in all direction of the movement are considered. During the calculating and creation of schedules of the train for site is used an analytical method of the solution of the differential equation of the movement of the train. For the analysis of optimum schedules of the train at each stage of their modeling an inspection of calculations which allows to guarantee reliability of the received results is car-ried out. For definition of potential opportunities of decrease in energy consumption on draft at traffic control of an electric train the concrete trip of an electric train of ED4M along a route Omsk - Irtyshskaya is analysed. Settlement schedules of an electric train are provided in the considered trip, and also with shutdown of one traction section. Average is defined by standard means of system of computer modeling on the way the electric train speed, dispersion of speed on the way, energy consumption. The received size of energy consumption for draft with the disconnected traction section is much less than energy consumption on a real trip. Rational distribution of time of the course of the electric train in all direction of movement from a condition of preserving time of its arrival also allows to reduce an electric power expense on draft by the terminal station. Based on consumption data of the electric power in general possible economy of energy costs on draft due to application of the offered methods is determined by Omsk TCh-31 depot.

    Loading of passenger trains in case of emergencycollision with a car on the railroad

    On the basis of the analysis of statistics of the incidents which have occurred on the railroads of Russia and connected with collisions of trains with obstacles, the most probable scenarios of development of an emergency situation are allocated. Modern methods of investigation of kinematics and dynamics of vehicles are analyzed. By methods of solid-state computer modeling the estimation of the dynamic loadings acting on the locomotive and passenger cars at collision of the passenger train with an obstacle in the form of the lorry on the railway crossing is carried out. For this purpose solid-state computer model of a passenger train and a cargo car. The obtained results indicate a high dynamic load of the locomotive in a collision. At the same time, passenger cars are affected by low dynamic loads that do not lead to damage to the load-bearing structures of passenger cars. The obtained results can be used in the creation of modern passenger rolling stock, characterized by high demands on safety in emergency situations. The work was carried out within the grant of the President of the Russian Federation for the state support of young Russian scientists MK-2881.2018.8.
