系统的位置有激励点(source)、路径点(transition)、接收点(receiver),但是看到下面就不明白了。
1:Choosing response data measured on different sources as input signal allows to separate a measured output responses, at for example the driver’s ear, in the different source contents.
2:Choosing several responses on one excitation source as input variables allows the identification of how the source’s excitation propagate into its neighboring component(s).
3:Using transition locations as OTPA inputs allow one to determine which locations transmit vibration the most. They do not indicate the origin of the source.
4:Using additional responses within the structure allows to identify how the vibration is propagated into the vehicle through succeeding components.
