단일 집전판 적용 팬터그래프 기구학 해석 프로그램 개발

초록

Formulations for simulating trajectories of the pantograph and reaction forces at nodal points of the pantograph mechanism are presented to develop the mechanism analysis program for railway pantograph withone contact strip. By comparison between the developed program and Solid Works®, commercial CAD S/W for tilting angles of the contact strip simulated during its upward motions, the accuracy of the formulations is validated. An optimal pantograph mechanism can be obtained by using the developed program which can simulate the changes of major design parameters, such as tilting angles of a contact strip and driving moments of a lower arm, as the lengths of members are changed.
