为深入分析三轴车辆的转向行驶性能，建立车辆二自由度数学模型，根据模型对车辆转向性能进行计算分析。建立车辆虚拟样机模型并进行转向性能仿真，将所得结果与数学模型计算结果进行对比分析。通过实车试验对数学模型进行验证，并对虚拟样机模型加以修正。结果表明：根据所建立的二自由度数学模型以及修正后的虚拟样机模型得出的车辆转向性能能够较好地与实车试验结果吻合。

For analyzing the steering performance of three-axis vehicles further, the two degree of free?dom mathematical model was built and its calculation and analysis were finished. A virtual prototype model of the vehicle was set up, and the steering performance was simulated. The results from the test and calculation were analyzed contrastively. The mathematical model was validated by the real vehicle testing, and the model of virtual prototype was revised. The result shows that the testing results meet well with the vehicle steering performance from the two degree of freedom mathematical model built and virtual prototype model revised.
