Study on the influence of cornering characteristics of complex tread tires on rolling resistance based on finite element method

Abstract

The existence of tire slip angle and camber angle causes that the test results of conventional rolling resistance tester are often very different from the measured results installed on the vehicle. In addition, the test cost of rolling resistance tester with sideslip and roll is high. To solve the above problems, the effects of cornering characteristics on rolling resistance of complex tread tires were analyzed by finite element method (FEM). The numerical simulation model of a tire with complex tread patterns was established, and the reliability of the established numerical simulation model was verified by the experiments. The response relationships between tire lateral force, sideslip angle, camber angle and rolling resistance under multiple pure sideslip conditions and combined conditions were compared and analyzed, as well as the contribution rate of each tire component to rolling resistance under the corresponding conditions. The obtained research results can provide support for vehicle chassis adjustment and energy saving and consumption reduction in tire structure design.
