Numerical study on dynamic tire force estimation from measurement of vehicle body responses
For the identification of some bridge parameters,e.g.,modal mass,it is usually necessary to conduct simultaneous measurement of the excitation on the bridge and its corresponding bridge responses.However,traditional methods of the exciting the bridge by a hammer or shaker have many drawbacks including limitation on impact energy,narrow frequency range,as well as other site-specific difficulties.On the other hand,the vehicle-induced load can be used in the bridge parameter identification if the vehicle-bridge contact force is well estimated.In this paper,an algorithm is proposed to estimate the vehicle normal tire forces from the simple measurement on the responses at selected locations on a commercial vehicle.Kalman filter with the tire forces augmented in the system state vector is employed.The numerical examples are given,showing that the proposed algorithm has good accuracy and robustness against noises and modeling errors.
