Description
Summary:The paper deals with some new results obtained during a two-year research activity on a circular track, which was built in Czechoslovakia for testing the serviceability of different structural types of carriageways. During the testing process the influence on the growing dynamic response of three loading vehicles was also registered, so that experimental verification of the internal dynamic effects in the undercarriage system of loading vehicles according to the Czechoslovak hypothesis of the physical invariant dynamics could be obtained. This contribution presents the basic principles of the invariant theory. Very good agreement of the theoretical calculations with the experimental results on a typical two-mass dynamic system can be stated. For the prediction of serviceability of road pavements an empiricial relation has been derived based on statistical date obtained during a nearly one-year testing period.
