Abstract
Abstract A new experimental device has been produced in order to investigate creep force characteristics between wheels and rails. The device – called the Creep Tester –, which differs from traditional machines such as twin-disc rolling contact machines, is applicable to rails, and its wheel is capable of rolling on rails while using a specific mechanism to alter any longitudinal creepage generated. The Creep Tester is also equipped with a mechanism for setting yaw angles of wheel to induce lateral creepage. Along with a number of other features, such as a short measuring time and the ability to set normal forces, etc., the device is advantageous in ascertaining the parameters that affect creep force characteristics. Some experiments have been implemented, which represent the relationship between the longitudinal and lateral creep force characteristics under various yaw angle conditions.
