Abstract:

Energy demands are steadily increasing as the world's population continues to grow. Automobiles are primary transportation means in a large portion of the world. The combination of fuel consumption by automobiles along with the shrinking fossil fuel reserves makes the development of new more energy efficient technologies crucial. Electric vehicle technologies have been studied and are still being studied today as a means of improving fuel efficiency. To that end, this work studies the effect of switching frequency on the efficiency of a hybrid electric vehicle traction drive, which contain

Abstract:

This research is a railway industry related project, which is concerned with finding improvements in railway traction and wheel slip control in electric drives. A new approach was developed to detect the unknown and immeasurable rail surface. And a novel identification scheme was used to identify the best operating friction level. A new switching controller was operated by the induction motor controller under all possible train operating conditions. Aspects of the study were validated in the laboratory experiment. By exploring the in-rail track condition detection, the best drive torque and de

Abstract:

It is important to monitor the wheel-rail friction coefficient in railway vehicles to improve their traction and braking performance as well as to reduce the number of incidents caused by low friction. Model based fault detection and identification (FDI) methods, especially state observers have been commonly used in previous research to monitor the wheel-rail friction. However, the previous methods cannot provide an accurate value of the friction coefficient and few of them have been validated using experiments. A Kalman filter based estimator is proposed in this research project. The develope

Abstract:

After Michael Faraday invented the magnetism theory in 1821, the application of the permanent magnet machine was rapidly developed. The permanent magnet synchronous machine is one of the popular applications of electromagnetic theory, which is implemented in most electric vehicles nowadays. Since then, the trend of renewable electricity increased in order to reduce emission and electric vehicle popularity increased significantly. However, designing a motor that is able to rotate very fast for electric vehicle implementation is tricky. The cooling part is one of the important parts in order to

Abstract:

Insulating sheets, impregnants and encapsulation materials commonly used for winding insulation offer low thermal conductivities. This leads to an increased heating of the winding of electrical machines and to the existence of hotspots. The electromagnetical utilization of the machine has to be reduced with respect to the allowed maximum winding temperature. In this paper, the development and experimental investigation of novel polysiloxane composites with ceramic fillers are presented. The materials are tested by means of impregnated and encapsulated samples of a round-wire winding as well as

Abstract:

Independent-drive electric vehicles represent an advanced approach to vehicle dynamic control. The main feature of these systems is that they use traction motors that are independently connected to each wheel. This results in a shorter driveline, higher transmission efficiency, more compact packaging, and better utilisation of space. Combined with the torque information produced by electric traction motors, an independent-drive electric vehicle system is capable of performing traction control, antilock braking control and electronic power steering.

The performance of a combined vapor-compression cycle/ORC is evaluated using waste-heat from a diesel generator. A flat plate microchannel heat exchanger is employed to provide energy exchange between the diesel exhaust stream and an oil loop, which provides energy to a boiler. This study finds an increased diesel duty corresponds with an increased cooling capacity, for a maximum of 5 kW of cooling (with 13.5 kWe diesel load). System COP is reduced with a higher input power due to limitations in the cooling cycle. A number of solutions are identified to increase the COP and cooling capacity. A
