Calculation of Displacements of Vehicle Suspension on Tangent and Curved Tracks

A method is introduced in this paper to calculate the displacements of vehicle suspension when the train is running on tangent and curved tracks. This method makes use of the analysis of the displacement a point on a rigid body relative to reference coordinates, and calculates the displacement through coordinate transform. The reference coordinates are built on both the tangent and curved tracks. This method is accurate and simple.
