TRACK MAINTENANCE/RAILCAR SUSPENSION TRADE-OFFS TO OBTAIN ACCEPTABLE RIDE QUALITY

A methodology for combining vehicle suspension design with track maintenance requirements to provide an acceptable level of ride quality is presented. The emphasis is on minimizing the combined vehicle/track costs to maintain a specified ride quality. A general methodology is formulated that uses dynamic railcar computer models, models that relate maintenance/construction tolerances to track irregularity descriptions, available cost data that identify the cost of maintaining specified maintenance/construction tolerances, and ride quality specifications that relate the railcar vibration environment to passenger comfort. The methodology is illustrated by an example that analyzes the lateral dynamic response of a conventional passenger car to rail alignment irregularities.
