摘要
在振动理论与模态参数识别的理论基础上,对某舰艇整体的模态和振动进行测试,并对其动态特性进行评估,得出对工程实际有应用价值的结论,为船舶使用、预防性修理及其动态设计提供参考依据。
On the base of vibration theory and modal parameter identification, measurement of modal of the whole hull and vibration situation are conducted to evaluate the dynamic characteristics for a real ship. Some valuable results are obtained which are helpful to the ship＇s operation, preventive maintenance and structural dynamic design.
