工况传递路分析模型输入输出选取

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.


以上4条均没有说明输出(output)是谁。

有谁看明白的给解释一下,欢迎讨论

我先说说我的理解:
1 选择不同激励处的响应为输入(默认为接收处的响应为输出),研究输出中有哪些是由各激励传递来的,即separate a measured output responses in the different source contents。

2 选择同一个激励的多个响应为输入,可以识别激励是如何向邻近的部件传播,这一条我理解不了,因为还找不到合适的输出信号可以能够合理解释

3 选择路径上的响应作为输入(默认选择接收处的响应为输出),可以识别哪一条路径传播的振动最大,路径的响应并不代表激励源。

4 选择结构上额外的响应(作为输入,默认选择接收处的响应为输出),可以识别振动是如何通过这些部件传递到接收处。

关于第二条,不知还有没有更好的理解,抛砖引玉了。。
