A new shock absorber model for use in vehicle dynamics studies

The design of modern railway shock absorbers takes into account geometry, functionality, durability and strength. The working principles of a shock absorber are outlined. The development of a new shock absorber model for use in vehicle dynamics studies on comfort and stability is described. The model calculates the damper force as a function of the displacement and velocity of the piston rod in relation to the damper body. Modelling of the intake valves, damping valves, state variables, oil, oil flow components, and rubber attachments is described. The assumptions in the pressure model are outlined. The model makes it possible to analyse the dynamics and functionality of the shock absorber itself and the dynamic interaction with the vehicle. The state equations describing the oil flow to each working chamber, the coefficient C in the accumulation term, the effective compression modulus, the force on the piston and the position of the piston are presented.
