Abstract

The centrifugal pendulum vibration absorber (CPVA) is commonly used to suppress torsional vibrations in automotive shaft systems. The centrifugal double pendulum vibration absorber (CDPVA)—a specialized type of CPVA—consists of two pendulums mounted in series on a rotor. In contrast to the CPVA, the CDPVA can simultaneously suppress torsional vibrations of two orders without the need to shorten the pendulum to address higher-order vibrations. This study clarified the vibration suppression mechanism of the CDPVA using the natural frequency diagram. Its effectiveness in simultaneously suppressing vibration with two orders was verified experimentally. Additionally, the nonlinear effects of the CDPVA were investigated through experimental observations. In detail, a numerical model was developed using a multibody dynamics approach, and nonlinear analysis was performed using the shooting method. Using the tuning equation, two sets of pendulums were tuned to specific vibration orders using their moments of inertia. Because the pendulums in each set have different inertia ratios, each set has a different capacity for suppressing vibrations at different orders. Further analysis was conducted to illustrate changes in the system’s natural frequency diagram and to clarify the effects of excitation amplitude and pendulum damping on system stability. Finally, experiments were conducted to verify the effectiveness of the CDPVA.

离心双摆减振器同时多阶振动抑制实验验证

离心摆减振器（CPVA）是一种常用的汽车轴系扭振减振器。离心双摆减振器（CDPVA）是一种特殊的双摆减振器，由两个摆串联安装在转子上组成。与CPVA相比，CDPVA可以同时抑制两个阶的扭转振动，而不需要缩短钟摆来处理高阶振动。本研究利用固有频率图阐明了CDPVA的抑振机理。实验验证了该方法同时抑制两阶振动的有效性。此外，通过实验观察研究了CDPVA的非线性效应。采用多体动力学方法建立了数值模型，采用射击法进行了非线性分析。利用调谐方程，利用两组钟摆的转动惯量将其调谐到特定的振动阶数。由于每组钟摆具有不同的惯性比，因此每组钟摆在不同阶次上具有不同的抑制振动的能力。进一步分析了系统固有频率图的变化，阐明了激励幅值和摆振阻尼对系统稳定性的影响。最后，通过实验验证了CDPVA的有效性。

期刊介绍： The Journal of Sound and Vibration (JSV) is an independent journal devoted to the prompt publication of original papers, both theoretical and experimental, that provide new information on any aspect of sound or vibration. There is an emphasis on fundamental work that has potential for practical application. JSV was founded and operates on the premise that the subject of sound and vibration requires a journal that publishes papers of a high technical standard across the various subdisciplines, thus facilitating awareness of techniques and discoveries in one area that may be applicable in others.
