Abstract
Authors proposed a technique to improve the compliance characteristics of pantograph such as shifting the natural frequency of a pantograph-head and a technique for selecting suitable spring constant by using Genetic Algorithm. This is based on the dynamic model of pantograph in which the degree of freedom is increased and the effects caused by contact wire deviation, a pantograph-head interval and the pitching mode of a pan-head support can be examined. In this paper, the validity of this method has been performed through line test.
