This study defined the concept of the Healthy Living Support Center and analyzed its operation status and space composition. The Health Life Support Center is a newly created facility by separating the health culture projects from the Public Health Center. Therefore, it is differentiated from other public health service organizations that include medical practice. As a result, it can be seen that most of the spaces are composed of various health culture activities such as health education and health promotion rather than medical functions. In addition, it is regional specialization projects that play an important role in spatial composition of Healthy Living Support Centers. This study is meaningful in providing a reference for spatial composition and program operation in the future establishment of the Healthy Living Support Center.

A railway vehicle of the maximum speed of 400km/h is developed in Japan and the railway vehicle of the maximum speed of 350km/h is developed in Germany and France. According to the these tendency of high-speed of the railway vehicle, it is important to predict the dynamic performance of the vehicle. Because the stability and the safety of the vehicle can be confirmed through the prediction of the dynamic performance of the vehicle. In Korea, the next generation high-speed railway vehicle(HEMU-400X) which aims at the maximum speed of the 400km/h is developing. In this study, the model of the next generation high-speed railway vehicle(HEMU-400X) is created using ADAMS/Rail which is a commercial dynamic simulation program. Especially, an anti-roll bar and a Z-Link are modeled considering the effect of the vehicle kinematically. For evaluation of dynamic performance of the vehicle, a critical speed of the vehicle is examined through a stability analysis. Also, a maximum speed of the vehicle is evaluated through a dynamic analysis. These results will be helpful for a basic design of the next generation high-speed railway vehicle(HEMU-400X).

The railway vehicle consists of wires, bodies, bogies and wheelsets, and each part has very complex mechanism. In this paper, wheel-rail contact algorithm is implemented using C++ and inserted into the ODYN which is a dynamic analysis program. To analyze wheel-rail contact mechanism, information such as contact points, contact angle and rolling radius is calculated according to the wheel and rail profile. Using this information, a table for the calculation of the wheel-rail contact analysis is made according to the lateral displacement. And, the creepage and normal force are calculated and a creep force is estimated by the FASTSIM. To verify the reliability of the wheel-rail contact algorithm, results of the program are compared with the ADAMS/Rail and paper. Finally, a wheelset of the railway vehicle is modeled using ODYN and simulated static and dynamic analysis. And, to verify the reliability of the simulation results, a displacement, velocity, acceleration and force are compared with results of ADAMS/Rail.

Dynamic analysis is necessary for the High-Speed Railway vehicle which aims to run on max 400㎞/h. Especially, dynamic simulation using CAE(Computer Aided Engineering) can help to reduce the time of development of the High-Speed Railway vehicles. Also, it helps to reduce prices and improve the quality such as safety, stability and ride. There are many dynamic software for a railway vehicle, such as Vampire and ADAMS-Rail. There are limitations for each software and difficulties to analyze overall dynamics for entire railway system. To overcome these limitations, in this study, a program which can simulate entire railway vehicles was developed. This program is easy to use because it was developed using C++, which is object-oriented programming language. In addition, the basic platform for the development of dynamic solver is prepared using the nodal, modal coordinate system with a wheel-rail contact module. Rigid, flexible and large deformable body systems can be modeled by a user according to the characteristic of a desired system. Its reliability is verified by comparison with a commercial analysis program.
