The invention discloses a vibration testing device and method for a tower crane boom, and the device comprises a fixed disc and a bottom plate, a rotating arm is disposed above the fixed disc, the rotating arm is movably disposed in the middle of the fixed disc through a movable mechanism, and the bottom of the rotating arm is provided with an electromagnetic block close to each of the two ends. A plurality of magnetic attraction blocks matched with the electromagnetic blocks are evenly distributed at the upper end of the fixing disc, three sets of acceleration sensors are arranged at the upper end of the rotating arm, and a rotating mechanism used for driving the rotating arm to rotate is arranged below the fixing disc. Different vibration data can be received through the three acceleration sensors, the data difference value of every two adjacent acceleration sensors can be obtained, and the position of a vibration source can be obtained by calculating multiple sets of data; the rotating arm is driven to rotate through the rotating mechanism, so that the three sets of acceleration sensors at the upper end of the rotating arm change the measuring position and angle, vibration measurement is conducted again through the three sets of acceleration sensors, and vibration measurement is more accurate.
本发明公开了一种塔吊起重臂的振动测试装置及方法,包括固定盘和底板,所述固定盘上方设有转臂,所述转臂通过活动机构活动安装在固定盘中部,所述转臂底部靠近两端均设有一个电磁块,所述固定盘上端均匀分布有多个与电磁块匹配的磁吸块,所述转臂上端设有三组加速度传感器,所述固定盘下方设有用于驱动转臂旋转的旋转机构。本发明通过三个加速度传感器能够接收到不同的振动数据,能够得到相邻两个加速度传感器的数据差值,通过对多组数据进行计算能够得到振动源的位置;通过旋转机构驱动转臂转动,使得转臂上端的三组加速度传感器改变测量位置和角度,并通过三组加速度传感器再次进行振动测量,使振动测量更加精准。
