It is also observed that the representation of the transducer response by means of a single degree of freedom viscously damped system for frequencies near and higher than its natural frequency, is not adequate. 同时观察到,用单自由度粘滞阻尼体系表示感传器的反应,对于接近于和高于自振频率的频率是不适当的。
The damped blades is a nonlinear dynamic system, so its natural frequency can be influenced by external force. 与线性动力系统不同,阻尼叶片的频率不再是它的固有特性,其频率受外界激振力的影响。
