A static and a dynamic analysis model are separately established using ABAQUS finite element program to study the mechanical properties of track structure and running stability and safety of the vehicle under the condition that uneven settlement of bridge piers exists. The static model is aimed at studying the effects caused by uneven settlement alone and the dynamic one is for the effects indu...

Control Systems such as Anti Lock Brake Systems (ABS) and Traction Control Systems (TCS) are vastly used in most vehicles as to enhance the safety of the systems. These systems have many virtues on controlling the dynamics of vehicles, but they only control the longitudinal dynamics of the vehicle directly and the lateral dynamics of vehicle is not controlled because they do not receive any fee...

A concurrent multi-scale computational strategy for rail surface crack initiation analysis is introduced in current paper. It attempts to take advantage of the efficiency of macroscopic models and the accuracy of the mesoscopic models. The solving procedure is , through the coupling of individual approaches, beginning from the largest scale to the smaller scale, making use of multi-body dynamic...

With the development of global urbanization and construction regional urbanization, residents around urban cities are increasingly making demands on public transportation system. A new kind modern vehicle named Multi-Articulated Guided Vehicle based Virtual Track (MAAV-VT) with advantages beautiful, smart energy conservation environmental protection is proposed in this paper, which aims at opti...

By analyzing the measured corrugation data, cause of rail was discussed theoretically. Then, vehicle-track coupling model used to study stick-slip characteristics wheel-rail system. Finally, explained by combining modal analysis and relation. The transverse curve on inner rail-inner wheel leading wheelset presents a negative slope characteristic, which makes easy slide surface aggravates wear r...

Even before the IEEE’s Rail Transit Vehicle Interface Standards Committee (RTVISC) approved IEEE 1473, railcar manufacturers from Breda in Italy to Kinki-Sharyo in Japan to Bombardier in Canada had been designing the underlying LonWorks® protocol into their rail vehicles. But after its formal adoption in 1999, IEEE 1473-L based networks have begun to proliferate at transit properties in North A...

Abstract Passenger train products labelled as environmentally friendly now tend to be a requirement in world trade. Life Cycle Assessment (LCA) is method for quantifying environmental performance using the Product Category Rules (PCR) document guideline referring ISO 14027 standard. This study aimed determine methodological requirements PCR draft Indonesian Rail-Vehicle Industry by comparing an...

In the current situation, the automobile has become the main means of locomotion. It allows traveling long distances, encouraging urban sprawl. To counteract this trend, the train is often proposed as an alternative to the car. Simultaneously, the favoring of urban development around public transport nodes such as railway stations is one of the main issues of the coordination between urban plan...

Increased patronage of railways in the UK in the past 20 years has put demands on rolling stock to operate at peak availability with reduced time available for maintenance. One possible tool to enable this is the use of real time fault detection and diagnosis on board railway vehicles to detect faulty components and provide information about the current running condition of the system. This pap...
