The 1st report indicated that it is disadvantageous to the running vibration only to lower the friction coefficient of the side bearer from the present value as a countermeasure against the heavy wear of a wheel flange. This paper deals with the longituidnal elastic force and the friction one, which act in series as the resistance to truck turning, and also the lateral stiffness of the secondary spring. Generated random shapes of alignment irregularity are used in the analysis by the numerical simulation. Results shows that in the case of using the effect of reducing the lateral stiffness of the secondary spring it is possible to reduce the resistance to truck turning through the reduction of the longitudinal elastic force without deterioration of the riding comfort under both good and poor conditions of track irregularity.
