Bridge - friendly truck suspension

The paper deals with the development of the controlled track suspension that reduces the loading and deflection of a bridge on which a truck is passing. The trucks moving around the roads and bridges are causing their wear and damage. The mechatronical solution can help by the usage of controlled variable suspension damper that leads to the decrease of road-tyre forces and road damage. Such truck suspensions are called road-friendly track suspension. The concept of road-friendliness can be extended into the concept of bridge-friendliness. This paper investigates whether the road-friendly track suspension is also bridge-friendly and vice versa and even more whether there exists a specifically bridge-friendly truck suspension which reduces the bridge loading beyond that by the road-friendly track suspension. These concepts are studied within this paper on a complex nonlinear truck suspension model and multi DOF bridge model.
