摘要
介绍了通过理论计算得到桥式起重机的固有频率,用振动仪测试其实际振动波形,找到产生谐振的原因,并采取有效措施,消除谐振。
To introduce the natural frequency of bridge crane by theoretical calculation. The practical oscillating wave profile is tested by vibration gauge and the reason of resonance is found. Effective measures adopted and the resonance has been removed.
