I would like to ask you to review my study plan for KGSP scholarship. Thanks in advance.
admission in the Graduate School of Railway
Since my father worked his whole life in a train company, I have always had a keen interest in trains. Furthermore, after working as an intern in the R&D sector of Hyundai Rotem in South Korea, during my exchange year, I've decided to follow my academic career in Railway Vehicle Engineering area. Returning to Brazil, I started working as intern in the Brazilian Company of Urban Trains (CBTU), where I worked for 6 months in the train's maintenance sector. In my point of view, railway vehicles, and especially high-speed trains, are the future of world's transportation system, and my main objective is to become a specialist in Rolling Stock systems, being able to use my work for the development of the sector, and then improving people's quality of life.
During my graduation in Mechanical Engineering, I faced with a wide variety of subjects of study in this major, and I could grasp that every single subject in this field is either fascinating and immensely important for the society. However, throughout my graduation journey, I had a special interest about Dynamics, Kinematics and Control Engineering areas. Also, during a Motorcycle Engineering course, I had the opportunity of using those concepts for vehicle design, which was a mesmerizing experience for me. Yet, since my goal is to do research in Railway Vehicles, it is essential for me to learn the specific knowledge of rolling stock systems, and, due to the advanced level of complexity of this system, it is required more deep study, such as a master's degree. Hence, my goal of study is to learn the general rolling stock system's knowledge, and focus my learning in Railway Vehicle Dynamics. Seoul National University of Science & Technology is one of the few Universities in Korea that provides a specialized education regarding to railroad technology, and its Department of Rolling Stock System offers a differentiated curriculum and a focus on high-speed train design technology that totally fits my objective of study. Also, the department operates in collaboration with the Korea Railway Research Institute, which makes it an amazing opportunity to learn from the best railway experts in South Korea.
My research goal is regarding to the dynamic response of high-speed trains. A rail vehicle running at high speed tends to have a large amplitude vibration of the carbody, and this vibration can cause discomfort to the passengers inside the train. In this context, the vehicle's suspension system plays an important role to reduce the vibration to a tolerable level. Since the faster a train runs, the harder it is to provide a comfort ride, my objective is to analyze, via computational simulations, the dynamic performance of high-speed rail vehicles using different types of active suspension and control strategies, in order to reach a higher level of ride quality. Through the knowledge learned in classes and on-site activities, my aim is to use all my research potential to propose a suspension system that improves the ride quality for the passengers, and I hope that the results of my research can help the development of this technology.
In conclusion, I hope that my experience in railway industry and my academic achievements proves that I am a great candidate for admission in the Graduate School of Railway, and for receiving KGSP scholarship. Once I become a master student of the Department of Rolling Stock Systems at Seoul National University of Science & Technology, I will assure that my acceptance and the given scholarship will be worth.
