摘要
以某舰船模型为对象,利用CF—5220双通道频谱分析仪,采用宽频带的快速正弦扫描激励方法,对上述船模进行模态试验分析,同时利用模态分析软件的参数识别功能,结合三维数据转换程序,识别出该船模的各阶固有频率,振型以及阻尼参数,并以图表、曲线、动画等形式给出相应的结果。依据试验得到的结果,对舰船的振动特性进行了分析。
Modal experiment was carried out on a warship ment, the model was stimulated by the fast sinusoidal scanning The modal parameter identification of modal analysis software natural frequencies, vibration modes and damping. The results model to analyze its vibration characteristics. In the experi. incentive generated from CF-5220 FFT spectrum analyzer. and 3-dimensional data transfer were used to recognize the were displayed in forms of chart, curve and animation.
