Evaluation of truck cabin vibration by the use of a driving simulator

A new method for generating very realistic road descriptions of real roads for simulations is presented. The method has been developed and used for modelling an existing road in Sweden, which is considered to be challenging for truck drivers due to large undulation and unevenness. Using an advanced driving simulator vibration forces have been recreated and analysed. Low frequency vibrations around 1 Hz are dominating and is of the order that would expected from driving on this road. Smaller vibrations of a higher frequency, 7n12 Hz, are also present. These could be front axle vibrations, but more investigations are needed to be more conclusive.
