摘　　要：以Adams与Matlab作为协同仿真平台,基于双振子模型LQG控制器设计,建立了稳定控制方案和技术路线.仿真结果表明:垂向悬挂具有与双振子类似的隔振效果.尽管有横向和纵向相关运动模态的非线性影响,转向架仍可以实行有源/无源控制.仿真研究可以证实,无源控制转向架的系统机制是通过阻尼控制强制(垂向)主导运动模态处于稳定状态.Based on the collaborating simulation/design between ADAMS and MATLAB,the design scheme and technical route of vertical stability control are established by double-oscillator LQG controller.Simulation results show vibration-isolation effect of vertical suspensions,which is familiar with the effect of double-oscillator.Although there is the nonlinear influence of lateral/longitudinal relevant vibration mode,the secondary suspensions in bogie can be regulated with source or non-source control.The simulating results also show that the machanism of non-source control in bogie is carried on by damping control which is able to force the vertical domaint vibration mode to be a stable conditions.
