Demonstration of Magnetostrictive Materials for Self-Powered Monitoring of Rail Vehicle Suspension Components

The purpose of the proposed project is to demonstrate the use of magneto-strictive materials for self-powered sensors in railroad suspension components. Results obtained in a previously funded University Transportation Center for Railway Safety (UTCRS) project have shown that Terfenol-D has the capability to harvest significant amounts of energy (on the order of 100 mW/cm3) under conditions typical of those found in railcar bearing adapters, and is also capable of acting as a real time load sensor. Both applications use the same mounting fixture and static magnetic field bias, indicating that a single Terfenol-D core could simultaneously provide load sensing as well as sufficient power generation to supply its own support electronics, multiple additional sensors, and a low-power radio frequency (RF) transceiver for wireless monitoring. The primary deliverable for this project will be an integrated, self-powered prototype comprising (a) a magnetostrictive core biased and packaged appropriately for mounting in or on a railroad bearing adapter, (b) support electronics simultaneously extracting power and providing calibrated load measurement, and (c) a basic wireless transceiver. The prototype will be tested in the UTCRS laboratory on a railroad bearing tester that closely simulates field service operating conditions.
