【摘要】 为实现不依赖于轮胎物理样胎的轮胎力学特性估计以及轮胎模型辨识，加速满足轮胎虚拟送样的技术与精度需求，本文基于有限元软件ABAQUS提出了轮胎侧倾转偏仿真的方法，并分析了侧倾角对转偏力学特性的影响。首先，进行轮胎有限元模型搭建，结合台架测试数据对模型的仿真精度进行验证，提出了使用隐式求解器的轮胎侧倾转偏仿真方法；其次，针对转偏特殊情况的原地转向工况，分析了侧倾角对原地转向回正力矩的影响；最后，进行不同载荷的侧倾转偏仿真，并分析侧倾角对转偏力学特性侧向力、回正力矩刚度区和全域的影响。结果表明，侧倾角使转偏侧向力、回正力矩刚度区具有明显非线性，且会影响转偏侧向力衰减速率、转偏回正力矩过渡区曲率等曲线特征。更多还原

【Abstract】 In order to realize the estimation of tire mechanical characteristics and the identification of tire models that do not rely on the physical sample of tires, and to accelerate satisfying the technical and accuracy requirements of tire virtual delivery, in this paper, based on the finite element software ABAQUS, a method for simulating the tire camber-turn-slip combined condition is proposed, and the influence of camber on the turn-slip is analyzed. Firstly, the tire finite element model is constructed, and the simulation accuracy of the model is verified by the bench test data, and simulation methods of tire camber-turn-slip combined using implicit solver is proposed.Secondly, According to the spin turn condition under the special case of turn-slip, the influence of the inclination angle on the spin turn aligning moment is analyzed. Finally, the camber-turn-slip conditions of tires with different load are simulated, and the influence of camber on the lateral force, aligning moment stiffness region and the whole area of the turn-slip mechanical characteristics are analyzed. It is concluded that the camber has a significant nonlinearity on the stiffness area of the lateral force and aligning moment, and affect the curve features of the decay rate of the lateral force, the curvature of the transition zone of the aligning moment and so on.更多还原
