Collision type rotary spring mass damper
The invention provides a collision type rotary spring mass damper which comprises a rotating shaft, a separation rotor is arranged on the rotating shaft, and the separation rotor comprises a separation plate rotating bearing and three separation plates; six eccentric rotors are arranged on the rotating shaft, and two eccentric rotors are arranged between every two adjacent partition plates; each eccentric rotor comprises an additional mass block, a connecting rod, a spring and an eccentric rotor bearing, an inner ring of the eccentric rotor bearing is fixedly mounted on the rotating shaft, one end of the connecting rod is fixedly connected with an outer ring of the eccentric rotor bearing, the additional mass block is slidably mounted on the connecting rod, the connecting rod is sleeved with the spring, and the spring is fixedly connected with the connecting rod. And the spring is connected between the eccentric rotor bearing and the additional mass block. The device is remarkable in energy consumption, does not need to additionally arrange a damping device, is beneficial to reducing space requirements, is insensitive to frequency change, does not directly impact a main body structure in collision, and avoids the adverse effects of acceleration surge, local damage and the like of the main body structure.
本发明提供了一种碰撞型旋转弹簧质量阻尼器，包括转轴，在转轴上设有分隔转子，分隔转子包括一个分隔板转动轴承和三个分隔板；在转轴上设有六个偏心转子，每相邻的两个分隔板之间分别设有两个偏心转子；各偏心转子均包括附加质量块、连接杆、弹簧和偏心转子轴承，偏心转子轴承的内圈固定安装在转轴上，连接杆的一端与偏心转子轴承的外圈固定连接，附加质量块可滑动的安装在连接杆上，弹簧套设在连接杆上，且弹簧连接在偏心转子轴承与附加质量块之间。本发明耗能显著，无需额外设置阻尼装置，有利于减小空间需求，对频率变化不敏感，而且碰撞不会直接冲击主体结构，避免了主体结构加速度激增和局部损伤等不利作用。
