SUBJECT: Evaluation
KEYWORDS: Coupler Lateral Angle, L/V Ratio, Spiral Length, Superelevation, Buff Force, Mathematical Model
ABSTRACT: Simple curve entries with/or without spiral for different curves are analyzed using the Quasi-Static Lateral Train Stability Model. The effect of spirals on maximum L/V ratios and coupler lateral angles in simple curve entries is investigated. The effect of buff force on lateral train stability in curve entries with spirals is studied for 2 to 16 degree simple curves.
