Abstract
Dealing with lightening is required to enable further speed-up and shortening of the arrival time, and the mass under the spring needs to be decreased in Shinkansen Rolling Stock. The increase of brake energy by the speed-up gives damage to the brake disk and brake lining.Therefore, these need a drastic change. So, brake disks made of aluminum metal matrix composite material was developed Full-scale aluminum composite brake disks were made and performance confirmation was done in the running test.
