某款A3汽车的轮胎试验数据，包括其纵向力、侧向力以及自回正力矩数据。根据这些数据绘制该A3车的轮胎特性曲线。-Tire test data to a subsection A3 car, including its longitudinal force, lateral force and self-aligning torque data. These data are plotted according to the tire characteristic curve A3 car.

采用空间坐标转换的方法分别求出了轮胎纵向力、侧向力以及垂直载荷产生的绕主销的回正力矩表达式。-Spatial coordinate transformation methods were calculated tire longitudinal force, lateral force aligning torque expressions and vertical loads generated around the kingpin.

dugoff轮胎模型 输出量：纵向力(N),侧向力(N)； 输入量：轮胎垂向载荷(N),轮胎滑转率,轮胎侧偏角(rad),轮胎纵向附着系数,轮胎纵向刚度(N/rad),轮胎侧向刚度(N/rad)- Dugoff tire model Output: longitudinal force (N), lateral forces (N) Input: vertical tire load (N), the tire slip rate, the tire slip

动力学软件仿真后，用于根据动力学结果计算轨道车辆轮轨横向力(After the simulation of dynamic software, the lateral force of the track vehicle is calculated according to the dynamic results)
