The invention relates to a pivoting type active control dynamic vibration absorber for inhibiting shaking of a railway vehicle, which is arranged on a chassis at the front end and the rear end of a vehicle body in pairs and comprises a signal acquisition system, a control system and a vibration reduction system, the vibration reduction system comprises a vibration absorption mass block, an opening type linear bearing, a bearing inner ring fixing rod, a bearing outer ring fixing rod, dampers, damper mounting bases and damper hinge pin bases. The actuator is connected with the two dampers through the damper mounting bases. The two dampers are hinged to the bearing inner ring fixing rod and the bearing outer ring fixing rod through damper hinge pin bases correspondingly. One end of the vibration absorption mass block is connected with the bearing outer ring fixing rod, and the other end is mounted at the bottom of the vehicle body through the opening type linear bearing and the bearing inner ring fixing rod. Compared with the prior art, damping force can act in multiple directions of transverse moving, head shaking and side rolling mode vibration of a vehicle body, shaking of the vehicle body is ingeniously and effectively restrained, and therefore the running stability and riding comfort of the vehicle are improved.

    本发明涉及一种抑制轨道车辆晃车的枢接式主动控制动力吸振器,成对设置在车体前端和后端的底架上,包括信号采集系统、控制系统和减振系统,减振系统包括吸振质量块、开口型直线轴承、轴承内圈固定杆、轴承外圈固定杆、阻尼器、阻尼器安装座与阻尼器铰接销座,作动器通过阻尼器安装座分别与两个阻尼器联结;两个阻尼器通过阻尼器铰接销座分别与轴承内圈固定杆和轴承外圈固定杆铰接;吸振质量块的一端连接轴承外圈固定杆,另一端通过开口型直线轴承和轴承内圈固定杆安装于车体底部。与现有技术相比,本发明可使阻尼力在车体的横移、摇头、侧滚模态振动的多个方向上产生作用,巧妙有效抑制车体的晃动,从而提高车辆运行平稳性和乘坐舒适性。
