DYNAMIC CRITERIA FOR THE DESIGN OF CONTACT LINES
If the running speed in a contact line/pantograph system is no longer low as referred to the velocity of the transverse waves on the contact wire, dynamic effects could develop, resulting in rapid wear of the contact wire and pantograph contact strips as well as in more serious arcing. These effects are caused by the amplification of contact wire oscillations propagating in direction towards the running pantograph on reflection at the contact strip. It is therefore proposed to supplement the known qualitative design criteria "maximum uniformity of steady-state elasticity" and "maximum possible accuracy of control" by the quantitative dynamic criterion "maximum reflection factor for transverse waves in catenary smaller than the Doppler effect factor of the moving pantograph". It is expected that contact line systems satisfying this criterion will give better running and lower wear at high running speeds than other known systems.
