摘要： A simulator is provided for verifying the proper operation of railroad rolling stock hot wheel detectors. The simulator includes heaters mounted on trucks of a railroad car, between the wheels and within the profile of the thickness of the wheels. Shock mounts, spring mounts and safety cables are used. An electromagnet is mounted on the heater to trip a sensor to activate the detector and a sensor on the car is used to determine the ambient temperature. Each heater includes a heater temperature sensor and is maintained at a constant temperature above ambient to approximate the thermal radiation of a hot wheel. Each heater is adjusted to direct heat horizontally outwardly from the truck to permit a hot wheel detector adjacent to and outside of the rail to detect a hot wheel. The car has two trucks with one heater on each side of each truck. One heater on each side simulates a temperature approximately equal to a hot wheel. The other heater on each side simulates a lower temperature and should not be detected as a hot wheel. The simulator can be integrated with a hot bearing simulator system.
