将最优化理论运用于铁道车辆蛇行运动稳定杜研究领域，建立了高速客车蛇行运动稳定杜最优化数学模型。在研究了多种优化算法的基础上，采用有效算法，以纵、横向轴箱定位刚度为设计变量，以高临界速度为优化目标，对给定高速客车预以实例计算。由双设计变量及目标函数构成的三维图和临界速度等值线图证实了解的正确性。
The optimization theory is applied to the research field of railway running stability, and the optimal mathematical model of stable running of high speed passenger car is established. On the basis of studying many kinds of optimization algorithms, an efficient algorithm is used to design the locating stiffness of the longitudinal and transverse axleboxes as design variables and the high critical speed as the optimization target. The three-dimensional map composed of double design variables and the objective function and the contour map of the critical velocity confirm the correctness of the solution.
