There are difficulties investigating the root underlying mechanisms of complex structural vibration for automobiles and other products, even with eigenmode analysis, due to the complexity of the mode shapes.
Unit mode analysis extracts simple shaped modes called "unit modes" from complicate eigenmodes, simplifies the overview of vibration transmission, and clarifies the dominant vibration paths between unitmodes
