PERIODICAL DYNAMIC STABILITIES OF A CATENARY-PANTOGRAPH SYSTEM

One of the most basic and fascinating problems has long been how to understand the periodic movement characteristics and the stability of a catenary-pantograph system. This paper studied theoretically the periodic steady state motion of the system using a model of an infinite string supported with equi-spaced suspensions and an upward force moving along a string with a constant velocity. In order to get to the solution, the authors applied the method originally developed by C. C. Smith and D. N. Wormley. At first, the resonant phenomenon happening at about a third or a half of wave velocity is discussed; secondly, the relations between the resonance and kinematic energy propagation on the wire system is described.
