The invention relates to a mass damper capable of automatically tuning. A system and method includes a mass damper for reducing vibrations in a structure or machine. The mass damper includes a frame that is linearly movable along a base that includes a track gear. The flywheel is in geared engagement with the track gear to be rotationally driven as the frame moves linearly relative to the base. A rotary damper is mounted on the frame and in geared engagement with the flywheel, the rotary damper generating a counter torque against rotation of the flywheel, the counter torque being proportional to a rotational speed of the flywheel. The rotary damper has electrical characteristics that are automatically adjusted to vary the counter torque and tune the mass damper. 本发明涉及一种可自动调谐的质量阻尼器。具体而言，一种系统和方法包括用于减少结构或机器中的振动的质量阻尼器。质量阻尼器包括可沿底座线性移动的框架，该底座包括轨道齿轮。飞轮与轨道齿轮处于齿轮传动接合，以便随着框架相对于底座线性移动而受旋转驱动。旋转阻尼器安装在框架上并且与飞轮处于齿轮传动接合，旋转阻尼器产生抵抗飞轮的旋转的反转矩，该反转矩与飞轮的旋转速度成比例。旋转阻尼器具有自动调整以改变反转矩并且调谐质量阻尼器的电特性。
