摘要
本文中基于车辆动力传动系统4自由度动力学模型,利用特征值灵敏度分析,获得影响各阶固有振动的关键转动惯量,确定共振频带附近激励时所需动力吸振器的安装位置。根据外部激励的宽频转矩模型与系统固有振动之间的关系,将振动频带切割分段,在相应频段的相应位置安装对应动力吸振器分段控制。然后对各个动力吸振器进行最优参数匹配设计,并对安装动力吸振器组的传动系统进行移频特性和固有振动能量分析,佐证减振机理。最后对安装动力吸振器组的传动系统进行瞬态振动分析,验证该方案对传动系统宽频减振的有效性。
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.
