Development of wheel profile automatic measurement device

Abstract

Wheel profile automatic measurement device was developed to keep ride comfort, perform wheel turning at the appropriate time, and manage wheels at a higher level. This device was designed to be highly accurate and compact enough to be installed in the main track for high frequency measurements. The accuracy of this device was confirmed to be adequate compared to the conventional method. Endurance test was conducted on this device to resolve various problems. Utilization of this device will result in lower costs and a higher level of wheel management.
