摘　　要：针对钢带式高速轮胎试验台运行时轮胎侧向力等引起的钢带不利的侧向偏移,采用了一种钢带主动跑偏方法,以实现传送钢带居中的目的.分析了钢带的主、被动跑偏相关机理以及跑偏控制的重要性,根据欧拉伯努利梁模型建立了钢带主动跑偏的六阶状态空间方程,提出钢带与转鼓刚柔耦合滞后改进模型.通过仿真与试验,验证了该模型分析的正确性,并给出了相关主动跑偏的一般规律.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.
