摘要
为了满足汽车动力学整车仿真的研究需要,基于Matlab/Simulink,用PAC2002魔术公式建立某轮胎动力学的仿真模型,对车辆稳态行驶时在轮胎纯驱动(制动)、纯转弯、驱动(制动)和转弯联合等工况下,分别进行纵向滑移率、侧偏角、垂直载荷等指标对纵向力、侧向力和回正力矩的仿真分析。仿真结果表明,基于PAC2002魔术公式的轮胎动力学模型能够比较准确地模拟出轮胎的动力学特性。
In order to meet the need to analyze the vehicle dynamics, based on the Matlab/Simulink software, a tire dynamics model is established according to the PAC2002 Magic-Formula tire model. Then the model is solved under the steady-state conditions such as vehicle pure braking, driving, pure cornering, braking, driving and cornering. The tire longitudinal force, the lateral force, and the aligning moment are caculated in different slip ratio, slip angle and the vertical load. It is shown that the tire dynamic model based on PAC2002 formula effectively simulates its dynamic characteristics.
