Non-linear steady-state curving analysis of some unconventional rail trucks

Modified railway passenger truck designs are considered to improve the compatibility between dynamic stability and the ability of the vehicle to steer around curves. A comparative study on the non-linear steady-state curving behavior 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.
