Abstract

The contact loss and wear of contact wire at overlap sections are larger than those in the normal areas of Shinkansen. It is important to modify overlap structures to reduce contact loss and wear of contact wire. We measured the height and wear of contact wire and acceleration produced on vibrating pantographs of a testing train at overlap sections of JYOETU Shinkansen to investigate the relationship between the height and the wear or acceleration. Furthermore we calculated current collecting characteristics of overlap sections by simulation. According to the results obtained, we can keep the wear rate of contact wire to an appropriate value by maintaining a constant height of contact wire.
