ANALYSIS OF THE LATERAL DYNAMICS OF A RAILWAY VEHICLE WITH SPECIAL REFERENCE TO BOGIE DESIGN

This study is intended to analyze the lateral dynamics including the hunting stability and the forced vibration of a bogie vehicle consisting of a 17-degrees-of-freedom system. The nonlinearities of the system are not taken into consideration to avoid the complexity of calculation. The equaltions of motion are derived from LaGrange's Equation, J. Kalker's creep theory is applied to evaluate the contact tangential forces and torques around the vertical axis acting between wheel and rail. For the analysis of the forced lateral vibration, sinusoidal misalignment of tracks is taken into consideration. Equations of motion are given in matrix form and numerical calculations are carried out by an electronic digital computer. The principal purpose of this study is to determine the optimum values of the design parameters such as the stiffnesses and the damping coefficients of each stage of suspension system (primary and secondary) of the bogie.
