Railroad cars, Design and construction
Mass transit vehicles in formal rail service frequently attain speeds which can excited carbody oscillations (primary hunting), as well as sustained lateral oscillations of the trucks (secondary hunting). The carbody motions have been shown to generate passenger discomfort and sustained truck hunting can lead to derailment. This thesis developed approximate equations which predict the carbody hunting frequencies, as well as the hunting speed of an articulated frame truck. The linear equations of motion are derived from a simplified model of a railway vehicle. A comparison indicates the results obtained using the approximate truck hunting equation presented here are within ten percent of the results obtained from more rigorous approaches reported by others.
