随机路面激励下车辆垂向振动微分几何解耦控制
Differential Geometry Decoupling Control of Vehicle's Vertical Vibration under Random Road Excitations
摘要
Abstract
The dynamic coupling mechanism between vehicle's suspension mass and non-suspension mass is analyzed. The 7-DOF nonlinear model of vehicles with passive suspension is established. The vertical vibration of the nonlinear model under random road excitations is analyzed by means of the method of differential geometry. After the decoupling, the nonlinear system becomes several independent linear subsystems, and the vibration of the suspension spring mass is not affected by the excitations of road surface any more. The simulation results before and after decoupling are compared mutually. It is shown that after the decoupling, the amplitude and frequency of the vertical vibration, pitch vibration and roll vibration of the vehicle's body are greatly attenuated. And the effectiveness of the decoupling algorithm is verified.关键词
