Portable Electronic Wheel Gauge

This project will develop and demonstrate an innovative, portable electronic wheel gauge (EWG) to accurately measure rail wheels. Objectives are to improve commuter rail passenger safety and improve ride quality in a low-cost, effective manner. This gauge will make use of cutting-edge 3-D imaging metrology and electromagnetic sensing technology. It will take all of its measurements--flange wear, height, and angle; rim height and distance from reference groove; and wheel diameter--in a matter of seconds, with a single application. The cost of wheel maintenance, including measurement, refinishing/truing, and replacement, is high in many rail operations. The costs of improperly maintained wheels include loss of traction and efficiency and wastage of power and fuel. If a wheel fails entirely derailments can occur. Current standard practice in wheel measurement is to use the steel finger gauge and its relatives, a design nearly 80 years old that is time consuming to use, and unable to measure some characteristics of wheels. International Electronic Machines (IEM)'s prior electronic wheel gauge uses old technology, is larger and cumbersome to use, and does not perform certain measurements which are important to rail transit.
