Abstract Simplify vibration model of double semitrailer train based on relevant ride comfort theory. Force analysis of every parts in system was carried out to consider the train ride comfort at the aspects of vertical and pitching vibration. Vibration differential equation was established in vehicle coordinate system based on Darren Bell principle. The power spectral density of road surface is chosen as the expression of road surface roughness, and the relation between spatial frequency spectrum density and time frequency spectrum density is defined, confirming the input spectrum for vehicle. Simulation speed is 70 km/h on B-class road. Seat, 30 cm at the end of the first cargo compartment, 30 cm at the end of the second cargo compartment were the three selected points to analyze ride comfort resulting from fifth wheel lead, suspension stiffness, suspension damping and tire stiffness. This research could provide technology support for improving ride comfort of double semitrailer train.
