Abstract: Modified railway passenger truck designs are considered to improve the comparability between dynamic stability and the ability of the vehicle to steer around curves. A comparative study on the nonlinear steady state curving behaviour of some unconventional truck designs reveals that a modified truck design in which the primary suspension in the leading axle is different from the trailing axle - known as the unsymmetrical suspension truck - has the potential to achieve overall superior performance compared to other truck models considered in this paper.
Keywords: creep coefficients; curving behaviour; dynamic stability; lateral stability; modified truck designs; NUCARS; passenger truck; truck stability; unconventional truck; unsymmetrical suspension.
