Report describes analytical approach to question of operational safety for six-axle locomotives. Essential mathematical elements are locomotive model with corresponding data on suspension characteristics, method of track-defect characterization, and quantitative measures for characterizing operational safety.
The operational safety of six axle locomotives is analyzed. A locomotive model with corresponding data on suspension characteristics, a method of track defect characterization, and a method of characterizing operational safety are used. A user oriented software package was developed as part of the methodology and was used to study the effect (on operational safety) of various locomotive parameters and operational conditions such as speed, tractive effort, and track curvature. The operational safety of three different locomotive designs was investigated.
