The Office of Research and Development of the Federal Railroad Administration (FRA) and the Volpe Center are continuing to evaluate new technologies for increasing the safety of passengers and operators in rail equipment. In recognition of the importance of override prevention in train-totrain collisions in which one of the vehicles is a locomotive, and in light of the success of crash energy m...

There are no optimal vibration damping designs for safe movement at the present stage of development high-speed rail transport. The purpose improving existing structures is their ability to simultaneously dampen both longitudinal and transverse vibrations. For dynamic research, an analytical method has been developed calculating stresses deformations sidewall frame electric locomotive bogie in ...

Modern train interval control systems contain communication channels between traffic organizers and the locomotive, using rail inductive as lines. The threads that make up these lines are an integral part of traction network and, therefore, current is channeled through them. Bearing this in mind, signals operate under conditions strong interference from current. At present, continuous automatic...

The article considers the issues of determining main technical and economic indicators shunting locomotive during its modernization by a hybrid power plant. analysis scientific practical works on impact railway transport environment increase efficiency locomotives due to design changes, which are aimed at reducing emissions. A model has been developed determine rational ecological energy charac...

Aiming at the operation conflict problem of multi-objective, multi-path and multi-vehicle relay during mine locomotive under complex geological conditions, a modeling method based on an object-oriented stratified timed Petri net is proposed. In order to load transport materials as object oriented, which are combined with rules time constraints, underground roadway route carried out. addition, g...

Locomotive robot based on tensegrity has recently drawn much attention due to its lightweight and flexibility. This article presents an improved numerical model for locomotive tensegrities. The previously used bar element struts is replaced by beam element, rigid joint consider more details of the tendon–strut connections. vector form intrinsic finite (VFIFE) method adopted formulate carry out ...

Locomotive planning has been a popular application of classical optimization models for decades, but with very few success stories. There are a host of complex rules governing how locomotives should be used. In addition, it is necessary to simultaneously manage locomotive inventories by balancing the need for holding power against the need for power at other yards. At the same time, we have to ...

This research examined the feasibility of applying Time Domain Reflectometry to the task of broken rail detection. The key innovation is to regard the track as a two-wire electrical transmission line, and then apply the same electrical pulse/echo technique that is commonly used to locate breaks and shorts in electrical cables. The aim of the proposed locomotive-mounted system is to allow each t...

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...
