고무타이어를 주행륜으로 사용하고 무인운전으로 운행되는 고무차륜 AGT 경량전철 차량의 성능최고 속도는 70km/h이고 운행최고속도는 60km/h로 차량 표준사양에서 결정되어 고시되었다. 그러나 차량이 운행되는 노선의 다양한 곡률반경에 따라 제한속도가 결정되어야 하고, 고무타이어가 손상된 경우를 가정한 안전 제한속도도 결정해야 한다. 본 논문의 목적은 설계 및 제작이 완료된 한국형 표준 고무차륜 AGT 경량전철 차량에 대해 운행노선의 곡선반경에 따른 제한속도, 고무타이어의 손상에 따른 안전 제한속도, 그리고 이상의 조건들에 대한 승객의 승차감을 해석하여 제안하는 것이다.(중략)

현재 개발이 진행 증인 한국형 표준 고무차륜 AGT 경량전철 차량의 개발시험은 크게 주요 부품에 대한 구성품 시험, 제작 완료된 차량의 완성차 공장시험, 시험선에서의 주행성능시험 둥 3단계로 나누어 실시된다. 이들 중 2번째 단계인 완성차 공장시험은 2량 1편성으로 설계 제작된 시제차량에 대해 개발 요구사항 및 요구사양의 만족도, 시험선에서 본격적으로 수행되는 주행성능시험 전에 인프라(전력공급, 주행선로)와의 인터레이스 만족도를 확인하는 단계이다.(중략)

Based on the design requirements(size, strength, structure, weight, and etc.) for the rubber-tired AGT vehicle, carbody made of aluminum alloy is designed. The analysis of strength and stiffness is performed in the designed carbody, which results in the modification for optimal shapes and structures. It consists of a under frame, side frame, roof frame, end frame and forehead frame. After the carbody manufactured, tests are performed, which are vertical load test, longitudinal compressive load test, twisting load test, twisting natural frequency measurement, bending natural frequency measurement and 3 points supporting test. Results of them can guarantee a structural safety.

Due to the absence of design guidelines for elevated light-rail structures in Korea, most elevated light-rail structures have been designed and constructed based on the design codes of conventional railway bridges and on the codes recommended by foreign vehicle manufacturers. This is the main reason why most elevated light-rail structures are massive or over-designed or poorly constructed economically. In this paper, the authors carried out field tests to analyze the braking forces caused by braking a train running at speeds of 50km/h, 60km/h, and 70km/h, acting on the elevated structures of rubber-wheeled Light Rail Transit (LRT) trains. The authors also briefly describe the analyzed results of the braking force acting on the substructures of elevated light-rail structures. The test-results presented here in this paper can be referenced when establishing design guidelines or standards for elevated structures of LRT systems.

This study was aimed to verify the stable interruption characteristics between power collector and 3rd rail type conductor rail for the Korean-standardized rubber-tired AGT light rail vehicle. At the test track for the Korean-standardized rubber-tired AGT light rail vehicle, interruption ratios, stresses, vibrations, and contact force variations were measured by test conditions, having various train speed. As the results, it was verified that developed 3rd rail type conductor maintains interruption characteristics, which can supply stable electric power.

The characteristic of “Korea LRT Carbody” is designed by using AED(All Extrusion Design) method. This is developed in Europe and be introduced in this paper minutely. The window type of “Korea LTR” has no supported frame, so the passengers ensure the outside view widely. The passenger's door will designed by plug type - This is the first time in Korea. In this report we have an object to the strength analysis for the carbody design. For the purpose of safety and lightening, we are going to research the section of thickness through optimization design.

The carbody of the Korean Rubber Tired AGT is small size and light weight comparing to existing electric railcars. For this reasons, car shape and arrangement of major equipments are limited. AGT is newly adopted mass transportation system in Korea. Therfore, it should be desined to appeal to passengers and create new passenger demand. To achieve this goal, the design concept of carbody is to be new design to coincide with passengers emotions. In this regard, we tried to meet this trends through manufacturing of scaled models and being
