The operation process of the traction asynchronous electric drive rolling stock may be accompanied by occurrence emergency modes, which are characterized current overloads and lead to damaging power circuits or mechanical part drive. Therefore, studying electromagnetic processes that occur in modes is relevant, particular, for developing systems aimed at diagnosing protecting equipment. Ukraini...

The modal analysis, which decouples the contact wire and rail track conductors, is used to develop an integrated model of single rail track and contact wire. The characteristic impedance and propagation constant matrices of integrated model have been computed. The authors have studied effects of various parameters of interest on characteristic impedance and propagation constant using sensitivit...

Hybrid electric vehicles employ a hydraulic braking system and a regenerative braking system together to provide enhanced braking performance and energy regeneration. In this paper an integrated braking system is proposed for an electric hybrid vehicle that include a hydraulic braking system and a regenerative braking system which is functionally connected to an electric traction motor. In the ...

Although motorcycle crash is one of the most common causes of death and injury, there hasn’t been a standard experiment system to simulate the generation of the resulting motorcycle impact injuries. A unique motor drive unit (MDU) and motorcycle crash simulation unit (MCSU) were developed to establish a short-track and high-accuracy experiment system of motorcycle impact injury. The control har...

Indian villages, towns and cities have high air and noise pollution caused by transport vehicles, especially petrol/dieselpowered three-wheelers. Conventional Internal Combustion Engine (ICE) driven 3 and 4 wheelers are against environment friendly and those are having very less efficiency when compared to EVs (Electric Vehicles). This paper details the overall construction and development of a...

Intelligent traction control system of an electric golf car has been developed by using the experience of the traction in order to maintain the golf car traction as required with utilizing optimum power. Compared with conventional control approach, fuzzy logic approach is more efficient for nonlinear dynamic systems and embedding existing structured human knowledge into workable mathematics. Th...

This paper presents an integrated traction control strategy (ITCS) for distributed drive electric vehicles. The purpose of the proposed strategy is to improve vehicle economy and longitudinal driving stability. On high adhesion roads, economy optimization algorithm is applied to maximize motors efficiency by means of the optimized torque distribution. On low adhesion roads, a sliding mode contr...

An analysis of the operating conditions traction drives an electric rolling stock with asynchronous motors was conducted. In process operation, drive both direct torque control and vector found to possibly experience unstable modes, in terms power supply load. The models locomotive either or were adapted account for possible presence aforementioned operational factors. As a result modeling, sta...
