摘　　要：轮胎侧偏特性的时域仿真是轮胎动特性的一个重要组成部分 ,所建模型可用于轮胎和车辆动特性的试验模拟和仿真研究。在利用试验模态参数建立的轮胎侧向非稳态模型基础上 ,推导了用于计算不同侧向输入的时域瞬态响应公式。计算了侧向位移和摆动角输入下的轮胎动特性的时域响应历程 ,计算结果与同一轮胎的试验结果符合较好 ,说明所建模型是成功的。推导和计算结果完善了所建立的动态模型 。Time domain simulation of tire cornering properties is an important part of dynamic tire analysis. A time domain model developed using experimental modal parameters to simulate tire and vehicle dynamic performance was used to develop the transient response equation for different lateral inputs. The model can calculate the time history of the tire cornering properties for different lateral displacement and yaw angle inputs. The calculated results are in accordance with ones of experiments and literatures. This modeling presents a complete tire dynamics model and shows that the method using experimental modal parameters can accurately predict tire performance.
