摘　　要：建立ADAMS/Car整车仿真模型并试验验证,在此基础上,以汽车因数T.B.为车辆瞬态特性的评价指标,以弹簧刚度和稳定杆直径为变量进行正交试验设计,仿真出不同侧倾刚度分布对应的车辆瞬态响应。最后,应用线性回归分析方法,得到瞬态特性与设计变量之间的回归方程,并分析了设计变量之间的交互作用影响,为车辆侧倾刚度的匹配提供了重要依据。The vehicle transient response was simulated according to different roll rate distribution by orthogonal method based on the vehicle model built and verified in ADAMS/Car, in which T.B. was used as an evaluation index, the spring stiffness and anti-roll bar diameter as design variables. Then, the regression equation between transient characteristics and design variables was gained by linear regression method. And the interaction between the design variables was analyzed. The research provides an important basis for matching vehicle roll rate.
