汽车高速移线操纵性能分析与优化

本文采用汽车操纵性能的闭环评价方法，分析了某轿车的六个结构参数（转向系综合刚度、前、后轴侧倾转向系数，质心至前轴水平距离与轴距之比，轴距及整车绕过质心铅垂轴的转动惯量）对其高速移线操纵性能的影响规律，并采用正交试验法与复合形法相结合的优化方法，得到了六个结合参数的更优组合。

Analysis and Optimization of High Speed Lane-change Maneuverability

Using closed-loop evaluation method, this paper analyses the effect of six structural parameters (overall stiffness of steering system, front and rear roll steer coefficients, the position of the center of mass, wheelbase, and yaw inertia) of a car on its high speed lane-change maneuverability. In addition, by using a optimization technique a combining orthogonal experiment method with complex figure method, the six structural parameters are optimized.
