As the mixed practice requirements of passenger and freight transportations for 160 km/h rapid freight bogies, the wheel dynamical load reduction solution was formulated explicitly. If the improved freight bogie is in speeding-up practices, the wheel dynamical load problem will occur naturally. The simulations of single-oscillator model based on mono-wheelset indicate that the dry friction damping of axlebox suspensions will impose the tight structural damping constraints upon the bouncing motion mode of carbody sprung-mass. Meanwhile the simulation researches of simplified half-vehicle model based on single-bogie find that whichever the damping techniques are adopted in the axlebox suspensions, dry friction or hydraulic hysteretic damping, to form the secondary rubber suspension should be taken as one of main adoptive conditions. To avoid the vertical vibration transmitting mechanism to be formed, the two-stage suspensions of rapid freight bogies have the following particularities, i.e., the vertical stiffness of secondary suspension is far greater than the one of primary suspension, and has the necessary proportional damping. Due to high-speed abrasion problems, the rapid freight bogies should be designed by applying the analogy method to select rationally the vertical damper configuration of axlebox suspensions, and to prevent from the lag-phase non-linearity negative influences of axlebox suspensions in tare vehicles.
