FIELD: railway transport.
SUBSTANCE: invention relates to railway transport and is designed to check up parametres of compression springs and select springs for freight car bogie spring sets. Proposed method comprises determining dependence of compression upon force applied for every checked spring, that is, compression-to-force ratio. Preset field of tolerances is used in plotting total aforesaid ratio. Bogie spring sets should comprise springs that feature close ratios.
EFFECT: reduced total compression-to-force ratio of spring sets.
