Imagine the Engine/Mount of the kitcar is in nodes number 4001 and 4002 of the below figure.
Find the FRF (Acceleration/Force, i.e. Output: Acc., Input: Force) on three following conditions.
1. Input is in single point at node #4001 in Z-axis.
2. Input is in points #4001 & #4002 in same phase (same direction in Z-axis).
3. Input is in points #4001 & #4002 in opposite phase (opposite direction in Z-axis).
*Note that the output points for all three conditions are nodes #4001, #4003,#4004,& #4006? You need to plot three figures and each figure will have four FRF graphs in it. This time, two pages report with font size of 12 is sufficient.
Note that your model will have different node numbers with this model. These nodes are given only to show you the nodes locations that you need to consider.
