Abstract
This paper describes a method for reducing vibration on target subsystems of a structure composed of several steel panels by using structural intensity concept. Firstly, we deduce the modal expression of flexural vibration energy and structural intensity to discuss these relations. The numerical simulation is carried out to present that the vibration energy distribution except the components with same order corresponds to the structural intensity distribution. Next we discuss the reducing vibration on target panels of the test panel structure with line connections from the point of structural intensity. It is demonstrated that the vibration levels on the targets can be reduced by localizing the structural intensity and energy distributions with adding damping on the whole structure and the use of thicker panels.
