DYNAMICS OF A HIGH-SPEED SLIDING POWER COLLECTOR IN CONSIDERATION OF SLIDING FRICTION

Considering the sliding friction force produced between a contactor and a rigid collecting rail with a randomly wavy surface, the paper deals with the dynamics of a sliding power collector for a very-high-speed railway (300-500 km/hr). An analytical model is formulated, which has two contact points and takes into account the pitching of a contactor, the stiffness of the sliding direction in a contactor support system, and the nonlinearity of the contact stiffness between a contactor and a rail. Mainly, the influences of the sliding friction and the contact stiffness on the dynamic characteristics, i.e., the etc., are investigated. The equivalent linearization etc. , are investigated. The equivalent linearization technique is applied in the analysis. To verify the analytical results, digital simulations are carried out by preparing the artificial collecting rail wave.
