Such a cab configuration is commonly referred to as \"soft-mounted cab/spl Gt/CLOSE\"/, in contrast to a \"hard-mounted cab\" that is rigidly attached to the remainder of the locomotive structure. To this end, the structural dynamics of a production locomotive cab are studied in a laboratory environment. The cab is excited by a hydraulic actuator in a manner closely resembling the input the cab is subjected to in the field. A series of tests are conducted to establish the vibration baseline of the cab, and to define how various parts of the cab vibrate. Next, the cab structure is soft mounted and the noise and vibration tests are repeated, in order to establish a comparison between the hard-mounted and soft-mounted cab. The results indicate that soft mounting the locomotive cab can result in substantial noise and vibration reduction at all locations in the cab, and therefore provide more crew comfort, less equipment damage, and possibly manufacturing cost savings. The paper provides a detailed description of the setup of the locomotive cab in the laboratory, and the results for some of the noise and vibration tests that were conducted on the cab.","PeriodicalId":174709,"journal":{"name":"Proceedings of the 2001 IEEE/ASME Joint Railroad Conference (Cat.

This study extends the results presented by the authors on the curving and hunting benefits of steerable co-cos, using an equivalent stiffness approach. Here, we provide a detailed analytical treatment of the differences that exists between the dynamic characteristics of steerable bo-bos and co-cos. Although there exists a number of anecdotal statements on the ability of steerable trucks in general, and self-steering trucks in particular, there exists no study that provides a thorough qualitative or quantitative analysis of the differences between the steerable co-cos and bo-bos. This study attempts to provide a qualitative analysis of the particular effects of the steering mechanism on lateral stability, curving performance, and traction ability of steerable bo-bos and co-cos. Upon providing a background on self-steering trucks, we describe the bo-bos and co-cos that are widely used by the railroads. Next, we discuss the concept of equivalent stiffness for the two types of trucks. Finally, we discuss the dynamic differences between bo-bos and co-cos, and the design features that must be considered in each truck to optimize their curving, hunting, and adhesion characteristics.","PeriodicalId":174709,"journal":{"name":"Proceedings of the 2001 IEEE/ASME Joint Railroad Conference (Cat.

To meet this demand, we have developed a train detection device by using microwave balise (COMBAT: computer and microwave balise aided train detection) which allows a low cost configuration. It features noncontact tracking train detection. This system is intended to take the place of the conventional track circuit. This system detects the existence and direction of the train at the detecting point (microwave balise installation site). Use of this system has enabled logically continuous existing/nonexisting detection in units of the block configured with the detecting point as a boundary. Furthermore, whereas the conventional track circuit is restricted to track existing(0)/nonexisting (1) detection alone, the new system ensures highly reliable detection because it uses a train ID for train detection. Accordingly, the function of this system allows a train control system of a high degree of safety to be designed with a simple system configuration. A field monitor running test is currently under way to check the COMBAT performance to evaluate train detection performance using microwave balises and to verify the train detection logic. This paper introduces the COMBAT system configuration, microwave balise and concept of COMBAT train detection.","PeriodicalId":174709,"journal":{"name":"Proceedings of the 2001 IEEE/ASME Joint Railroad Conference (Cat.
