In the structures of home appliances, living equipments, automobiles, railway cars, and so on, vibration energys generated by some exciting sources at some point are transfered. The energy vibrates structures particularity on bones and cover plates, and makes much noise. To solve those problems, up to the present, we have been reducing their exciting forces, avoiding resonant vibration, and giving high vibrational damping. To design the structure to give a rational unti-vibration characteristics, we must know flows of vibration energy in the plates, and control the flows. However, we don't understand how to design structures for vibration, considering their energy flows. In this investigation, we study the flows of structural vibration energy experimently, and then, some knowledge for dynamic structural design is obtained.
