Abstract

In this study, a modeling method is based on representing a road generation system with several rigid bodies, i.e, pad, shaft, torsional damper, oneway-clutch, gear system, and electricity generator. The simulation software is developed to evaluate the performance of a road generation system. It is used to determine parametric dimension for optimal design with the theoretically calculated results from the simulation software. The parametric dimensions are included as capacity, length, and angle of equipment. The transient responses at the conditions of low and high vehicle speed are compared with the calculated results as torque, power, out energy etc. Consequently, before manufacturing system, the analysis of simulation results shows that the proposed concept and system has efficiency and confidence.

본 연구에서는 도로용 발전장치 최적화 설계를 위해 실험과 수치해석을 다루었으며, 도로용 발전장치는 패드, 축, 토셔널 댐퍼, 일방향 클러치, 기어, 발전기 등의 여러 가지 기계요소를 포함한다. 본 수치해석은 도로용 발전장치의 성능을 평가하기 위하여 개발되었으며 소프트웨어에 의하여 이론적으로 계산된 결과값을 사용하여 최적화 설계의 변수인자를 결정하게 된다. 이러한 변수는 장치의 용량, 길이, 각도 등이며, 차량의 운전상태에 따라서 토오크, 출력 및 생성된 에너지값 등의 결과값을 비교하여, 도로용 발전장치를 설계하기 전 수치해석을 통해 제안된 개념과 시스템이 효율성과 신뢰성을 갖도록 한다.
