There are 10 spans which are composed of 4 spans of normal section followed by 2 spans of overlap, and again 4 spans of normal section. When height difference and pulling up quantity are larger than 30 mm, contact-loss rate shows a tendency to become larger. Maximum values of contact force are shown in Figure. It is likely that the greater the contact force, the larger the wear of contact wire because mechanical wear is superior to electrical wear at Shinkansen. These calculation results agreed with measured ones.
Measured results agree with simulated ones.
