摘　　要：操纵稳定性作为现代汽车的主要使用性能,既影响汽车驾驶的操纵方便程度,又决定着汽车的行驶安全,被誉为"高速车辆的生命线",对其的研究也越来越重要。文章介绍了国内外多轴转向技术研究概况,重点介绍了国内外多轴汽车的操纵稳定性研究情况。通过建立线性多自由度数学和动力学模型对多轴汽车操纵稳定性进行仿真分析。综述表明,重型汽车采用多轴转向技术可以有效地减小转弯半径,提高操纵稳定性和安全性能。As the primary performance of modern vehicles,it＇s important to do some research on handing and stability,which not only affects ease of manipulation of vehicle driving,but also determines the vehicle＇s driving safety. Handing and stability is known as ＂rhe lifeline of high-speed vehicles＂.The general situation of multi-axis steering technique at home and abroad is introduced in this article,especially the research on handing and stability about multi- axis vehicle.The vehicle handing and stability is analyzed by simulation experiment through the establishment of linear multiple degrees of freedom mathematical and dynamic models.The results show the turning radius is effectively reduced by using multi-axis steering technique on heavy trucks,then the handing stability and safety is improved.
