摘　　要：应用已有的车辆简化模型,借助反演设计理论,研究了缓和竖曲线的反演设计方法;探讨了依据车辆—路面耦合动力学模型的安全性和舒适性动力学评价指标,给出了缓和竖曲线反演设计的一般流程。该方法为开发宜人化路面CAD系统提供了理论依据。Based on a model of a quarter of a vehicle, an inverse design method of transition vertical curve has been researched by applying inverse design theory. The dynamics estimate index considering safety and comfort in alignment design is discussed. The index is obtained from coupling dynamics model of vehicleroad. The common process of inverse design of transition vertical curve is given. The method can provide theoretical guide for making pleasant road CAD system.
