摘要
本文以汽车力学参数试验台测出的数据为基础,通过建立轮胎侧偏角、车厢侧倾角、回正力矩与侧向加速度之间的关系,运用最小二乘法对测试数据进行非线性曲线拟合,找出了这些数据与汽车稳态转向特性之间的关系,并按国家标准GB/T13047-91中的有关规定对被测试车辆的稳态转向特性进行了评价。
On the base of the data measured on automotive mechanics parameters tester, through setting up a relationship between lateral angle of tire, body roll angle, aligning torque and lateral acceleration and using method of least square, for curve fitting on non-linear data, a relationship has been found between these data and stable steering characteristics. The related steering characteristics have also been evaluated according to the national standard GB/T13047-91.
