固定旋转机械引起的结构振动及其减、隔振控制是设备减、隔振领域一个十分重要的研究课题.以往的研究主要关注结构的竖向振动,而结构水平向振动往往被忽略.论文以设置有固定旋转设备的单层框架结构为例,分析了结构水平和竖向动位移幅值与结构固有频率、设备安装位置及设备运转频率之间的关系.研究结果表明,在特定条件下,结构水平向振动响应可能大于竖向振动响应,这一现象在设计时应引起足够的重视.
Structure vibration caused by fixed rotating machinery and its control of vibration reduction and vibration isolation are a very important research subject in the field of equipment reduction and vibration isolation.The previous researches mainly focused on the vertical vibration of the structure and the horizontal vibration of the structure was often neglected.The dissertation Taking the single-story frame structure with fixed rotating equipment as an example, the relationship between the horizontal and vertical dynamic displacement amplitude and structure natural frequency, equipment installation position and equipment operating frequency is analyzed.The results show that under certain conditions, Structural horizontal vibration response may be greater than the vertical vibration response, this phenomenon should be given enough attention in the design.
