A nalytical Modeling and Simulation of Tire Non-uniformities

This research aims to analyze generated forces due to tire non-uniformities. Ideally, tire should be uniform in geometry, stiffness, and mass distribution. Thus, tire will rotate with no excessive force and/or vibration as vehicle moves. But it is only theoretically possible; in fact tire has some different kinds of non-uniformity. In this paper an analytical method is proposed to calculate force alterations in each case of non-uniformity. Then, importance of each case and also significant parameters are analyzed.
