振型(Modeshape)
一种振动振幅分布形态,用于表征具有特定尺寸的谐振器的某一特定模态。即使对应的模态不变,振型也可能随谐振器尺寸的变化而改变。
可以用人来作类比。一个人从婴儿长成成人,其外貌(振型)会发生变化,但这个人本身(模态)并没有改变。
Modeshape
An amplitude pattern of vibration that characterizes a particular mode for a resonator with specified dimensions. The modeshape may change as the resonator dimensions change, even though the associated mode does not change.
Consider an analogy to a person. The appearance (the modeshape) of the person changes as he grows from infant to adult, even though the person (the mode) does not change.
