Aim & Scope

The Journal of the Korean Society for Railway (JKSR) launched in 1997 aims to provide a platform to exchange research information, establish and pioneer railway-related academia, and present research results that are both practical and unique. The journal covers various research results, derived from theory and experiments, on topics related to railways such as railway policy and management, railway facilities, carriage machinery, electrical signals, and track engineering. It includes research outcomes that can contribute directly to the improvement of railway technologies as well as innovative studies on fundamental areas that can be applied to railways including mechanics, electricity, civil engineering, logistics, management and so on. The themes addressed by the journal include, but not limited to the following: -Rolling stock & Mechanical systems (materials, fracture, non-destructive testing, mechanics of materials and structures, design, dynamics and control, noise and vibration, heat and fluid mechanics, energy and power engineering, system engineering, reliability, maintenance, safety, etc.), -Power & Signal systems (power engineering and systems, electrical devices, circuits and systems, materials and devices, control and measurement, automation, signal processing, electrical and information communication, reliability, maintenance, safety, etc.), -Civil engineering for railway (structural engineering, material engineering, dynamics, seismic engineering, geotechnical engineering, measurement, geodetic survey, mapping, GIS, construction, architectural and environmental engineering, transportation engineering, etc.), -Transportation policy & Operation (railway traffic planning and engineering, railway management policy, railway technology policy, railway logistics, railway operation, railway information system, railway culture, etc.).

    In this paper, descibed was the derived algorithm for calculating contact point between wheel and rail and the developed method for rail modeling. The proposed methods use travelling distance to represent rail center line position vector and rail orientation with respect to Newtonian reference frame. The methods call be easily used ill multibody dynamic analysis. Two numerical examples are shown to verify the validity of the proposed methods.

    This paper presents a new algorithm to determine the pre-loads that sustain the static equilibrium state in a given position. The algorithm which uses a partial velocity matrix leads to an unconstrained optimization problem to compute the pre-loads of the suspensions. To demonstrate the validity of the proposed algorithm, the static analysis results that employ the pre-loads of three examples are presented using a reliable commercial program. Results of the analysis confirm the validity of the proposed algorithm.

    A high speed train named Korean High Speed Train (KHST) with its maximum operating speed 350 km/h is now under development. For the successful design of a quiet and comfortable high speed train, it is important to understand the general features of the noise and vibration characteristics of high speed train. This paper reviews extensively collected materials on the noise and vibration characteristics of existing high speed trains. Based on the noise and vibration characteristics of TGV systems, a simple indoor-noise prediction rule is proposed for the TGV-type high speed trains such as KHST The indoor-noise of KHST at 350km/h is expected to be larger than at least 71 dBA. Some important researches conducted for designing KHST during last two years under the G-7 project are also briefly introduced at the last part of this paper.

    The acoustic power reduction method can be used to design a quiet structure. To calculate the acoustic power radiated from a vibrating structure, the dynamic responses have to be determined. It is not easy to analyse the structure composed of the corrugated panels because of the structural complexity and the long analysing time. To make up for these defects, the equivalent orthotropic panel is presented. Also the acoustic power prediction method of the vibrating structures is proposed. As examples, the equivalent material properties of the corrugated plates are obtained and the acoustic powers of the floor structure are calculated at several frequency regions for the Korean High Speed Train.

    The basic idea of cable-stayed girder bridges is the utilization of high strength cables to provide intermediate supports for the bridge girder so that the girder can span a much longer distance. In the cable-stayed bridge, the cables exhibit nonlinear behavior because of the change in sag, due to the dead weight of the cable, which occurs with changing tension in the cable resulting from the movement of the end points of the cable as the bridge is loaded. Techniques required for the static analysis of cable-stayed bridges has been developed by many researchers. However, little work has been done on the dynamic analysis of such structures. To investigate the characteristics of the dynamic response of long-span cable-stayed bridges due to various dynamic loadings likes moving traffic loads. two different 3-D cable-stayed bridge models are considered in this study. Two models are exactly the same in structural configurations but different in finite element discretization. Modal analysis is conducted using the deformed dead-load tangent stiffness matrix. A new concept was presented by using divided a cable into several elements in order to study the effect of the cable vibration (both in-plane and swinging) on the overall bridge dynamics. The result of this study demonstrates the importance of cable vibration on the overall bridge dynamics.

    In this paper, made was a study on a mesh generation method based on the pollution error. This method is designed for the control of the pollution error in any patch of elements of interest. It is a well-known fact that the pollution error estimates are much more than the local one. When the pollution error is significant, nothing can be said about the reliability of any estimator based on local computations in the patch. Reliable a posteriori error estimation is possible by controlling the pollution error in the patch through proper design of the mesh outside the patch. This design is possible by equally distributing the pollution error indicators over the mesh outside the patch. The mesh generated from the conventional feedback pollution-adaptive mesh generation algorithm needs many iterations. Therefore, the solution time is significant. But the remeshing scheme in the proposed method was used here. It was shown that the pollution-adaptive mesh improves the E.I., simply denoted as Effectivity Index, on the patch of interest, and the pollution error reduces less than the local error.

    The durability of ballast plays an important role in track behaviour. To estimate the deterioration characteristics of ballast, several tests have been carried out by several scholars. The deterioration characteristics is very important factor in the behaviour of track and its life. In this paper, abrasion/breakage characteristics of ballast is studied to see the effect of physical ballast characteristics on ballast life. To reveal breakage characteristics of ballast, the ballast box test and the MTT field test were carried out. The breakage characteristics studied in this paper is applied to the ballast life prediction in various conditions, such as LA abrasion, annual tonnage, tamping number per year, etc
