Track/Train Dynamics and Design e-bog

Track/Train Dynamics and Design: Advanced Techniques reviews the progress that has been made in the development and applications of advanced analytical techniques for improving the dynamic stability, safety, and reliability of current generation rail freight vehicle components and track structures. Topics covered range from structural mechanics and stress analysis methods to and material science techniques for the prediction of fracture and wear in railroad applications. The nature of technology transfer from other application areas, notably aerospace, is considered, along with the unique nature of some railroad problems. This book is comprised of 26 chapters and opens with an overview of Phase II of the Cooperative Track-Train Dynamics Program, including its main goals, tasks, and progress. The reader is then introduced to the state Of the art of rail analytical techniques and cost/benefit issues associated with railways and railroad transportation. The following chapters explore body centerplate fatigue cracking; mathematical models for track/train dynamics; wheel and rail wear during freight car curving; and application of advanced stress analysis techniques in the design of freight car components. The application of finite element analysis to the study of railroad wheel failure phenomena is also outlined. This monograph will be a useful resource for transportation and mechanical engineers, especially those dealing with railroads.
