Steel Strip Active off Tracking of High-Speed Tire Test Rig

In order to compensate for the lateral displacement of the steel strip caused by the lateral force of the tire when the tire runs on high-speed steel strip tire test rig, a method of active off tracking was proposed to achieve the desired results of the strip in the middle. The control importance and mechanism of steel strip off tracking actively and passively were analyzed. A mathematical model about a six order state space equation was established based on the principle of Euler-Bernoulli beam. A hysteresis improved model was proposed coupling rigid flexible between belt and drum. The rationality and correctness of mathematical model were validated by simulation and experiment analysis. General rules of steel strip active off tracking were presented for real-time adjustment of the steel belt on test rig.
