摘　　要：侧偏刚度是决定操纵稳定性的重要参数。从轮胎模型和运动分析、整车运动和受力分析两方面介绍了客车动力学模型。探讨了如何估算动载荷作用下客车的侧偏刚度,并以国产 SX6120A 型豪华大客车为例,仿真得到了轮胎的侧偏刚度。Tire cornering stiffness is a key parameter of vehicle handling and stability.From two aspects of the tire model and kinematical analysis,vehicle kinematics and force analysis,the bus dynamics model is introduced.How to estimate the tire cornering stiffness under dynamic load is discussed.And with a home made SX6120A luxurious bus as the example, its tire cornering stiffness is simulated.

关 键 词：动载荷 轮胎 侧偏刚度 仿真
