摘要
建立了横向主动悬挂的17个自由度计算模型,将主动控制铁路车辆的横向平稳性问题,归结为线性二次型最优问题(LQ问题)求解。计算分析了铁路车辆在采用主动悬挂后横向平稳性改善的情况。计算结果表明,与被动悬挂相比。
A calculation model of lateral active suspension for railway vehicles with 17 degrees of freedom is established. To improve the lateral stability of an active suspension is considered to solve a linear quadric problem. Calculations are conducted to examine the improvement by employing the active suspension. It is shown that, compared to those by passive suspension, the root mean square values of the lateral acceleration and the interactive force of wheel rail decrease about 60% and 20% respectively.
