Determination of the load carried by each bearing in a railcar system is crucial to the integrity of the railroad industry. With accurate load measurement, the process of filling a railcar with its specified cargo can be optimized to provide the maximum amount of cargo without exceeding the upper weight limits imposed by the Associations of American Railroads (AAR). An accurate load measurement will additionally make it possible to identify any load imbalance that occurs during periods of travel which result in having a detrimental effect on the health of the bearing. Previous work conducted with a strain-gauge load sensor suspended between a thermoplastic polyurethane steering pad and a bearing adapter provided data that was accurate for dynamic rail conditions. This thesis will optimize the previous work performed by developing a multivariate calibration procedure suitable for field implementation.
