近年来，高功率和低气缸发动机的使用越来越广泛。这些发动机由于发动机燃烧而产生强烈的扭转振动。此外，自动变速器需要使用锁止离合器系统，该锁止离合器系统在发动机转速低时直接连接发动机和齿轮系。在变矩器中使用称为锁止阻尼器的扭转弹簧不足以吸收扭转振动。因此，离心摆吸振器（CPVA）已被开发来抑制扭转振动。CPVA的固有频率与发动机转速成比例，期望在宽的速度范围内抑制扭转振动。然而，当CPVA的振动幅度较大时，由于非线性，CPVA的固有频率发生变化。本文研究了CPVA抑制发动机扭振的最佳路径。
In recent years, high-power and low-cylinder engines have seen increasingly widespread use. These engines produce a strong torsional vibration due to engine combustion. Furthermore, automatic transmissions necessitate the use of a lock-up clutch system that directly links the engine and gear train when the engine rotational speed is low. Using a torsional spring called a lock-up damper in the torque converter is not sufficient to absorb the torsional vibration. Therefore, the centrifugal pendulum vibration absorber (CPVA) has been developed to suppress the torsional vibration. The natural frequency of a CPVA is proportional to the engine rotational speed, and it is expected to suppress the torsional vibration over a wide range of speeds. However, the natural frequency of the CPVA varies because of the nonlinearity when the vibration amplitude of the CPVA is large. In this study, the optimal path of the CPVA to suppress the torsional vibration of the engine was investigated.
