中文摘要:
      介绍轮胎侧偏刚度及力的特征函数及其应用。结果表明：随着轮胎侧偏刚度的增大，车辆在任何给定横向加速度下所需的侧偏角减小，车辆操控稳定性能更好；在匹配轮胎和车辆的操控稳定性时，可以通过侧偏角为1°时的轮胎侧向力系数、负荷灵敏度和侧偏角为4°时的轮胎负荷转移灵敏度的特征值进行轮胎结构、花纹、配方的优化，筛选出合理的设计方案；车辆稳定性系数越大，车辆不足转向性能越好。
英文摘要:
      Tire lateral stiffness and characteristic functions of force and their applications were introduced.The results showed that as the tire lateral stiffness increased，the required slip angle of the vehicle under any given lateral acceleration decreased，resulting in better handling stability performance of the vehicle.When matching the handling stability performance of tires and vehicle，the tire structure，pattern，and formula could be optimized through the characteristic values of tire lateral force coefficient，load sensitivity at the side slip angle of 1°，and tire load transfer sensitivity at the side slip angle of 4°，and a reasonable design scheme could be selected.The larger the vehicle stability coefficient was，the better the understeer steering performance of vehicle was.
