Abstract
Based on the 4-DOF dynamic model of the vehicle powertrain system, the key moment of inertia affecting the natural vibration of each order is obtained by eigenvalue sensitivity analysis, and the installation position of each dynamic vibration absorber required for excitation near the resonance frequency band is determined. According to the relationship between the wideband torque model of the external excitation and the natural vibration of the system, the vibration frequency band is segmented and the corresponding dynamic vibration absorber is installed in the corresponding position of each frequency band for segmentation control. Then, the optimal parameter matching design is carried out for each dynamic vibration absorber, and the frequency shift characteristic and the natural vibration energy of the powertrain system with the dynamic vibration absorber group are analyzed to prove the vibration reduction mechanism. Finally, the transient vibration analysis of the powertrain system with the dynamic vibration absorber is carried out to verify the effectiveness of the scheme for the wideband vibration reduction.
