摘要: 针对宽频强激励下车辆动力传动系统多模态扭转振动,开展自调谐变刚度扭转振动抑制技术的研究。介绍了所提出的并联变刚度调频复合扭转减振器的工作原理,建立了含扭转减振器的扭转振动系统动力学模型,分析了扭振系统在调频过程中固有振动特性的瞬态变化状态,提出了适合系统运行条件的并联变刚度频率调谐复合扭转减振器吸振组块的最优调频控制方案,搭建扭转减振器频率调谐方案验证试验台,对扭转减振器进行半主动控制试验,测试其固有频率对外部激励频率的跟随特性。研究结果表明,自调谐变刚度吸振组块可有效提高扭振系统的减振性能,改进后的频率调谐方案可以更好地降低扭振系统振动响应,且半主动扭转减振器在整个频率调谐范围,减振效果要明显优于被动减振器,验证所提频率调谐改进方案的有效性和可靠性。

Abstract: Research on self-tuning variable stiffness torsional vibration suppression technology is conducted to address multi-modal torsional vibration in vehicle powertrain systems under wideband excitation. The working principle of the proposed parallel variable stiffness frequency-tuned compound torsional damper is introduced, the dynamic model of the torsional vibration system with the damper is established, the transient changes of the inherent vibration characteristics of the torsional vibration system during frequency tuning is analyzed, the optimal frequency tuning control scheme for the parallel variable stiffness frequency-tuned compound torsional damper absorber block that is suitable for system operating conditions is proposed, a torsional damper frequency tuning validation test bench is constructed, semi-active control experiments on the torsional damper are conducted, and its frequency tracking characteristics with respect to external excitation frequencies are tested. The research results show that the self-tuning variable stiffness absorber block can effectively improve the vibration reduction performance of the torsional vibration system, and the improved frequency tuning scheme can significantly reduce the vibration response of the torsional vibration system. Moreover, the semi-active torsional damper performs significantly better than the passive damper throughout the frequency tuning range, which verified the effectiveness and reliability of the proposed frequency tuning improvement scheme.
