Summary:

Vibration reduction of the large space structure to meet its operational requirements was achieved by using the modal contribution indicator, which is defined as the percent contribution of each mode to the total response. The modal contribution indicator is related to the modal force participation factor and may be thought of as a measure of the extent to which the normal mode participates in synthesizing the load on the structure. Further more, a cross modal contribution indicator was defined to optimally reduce the vibration levels for a structure subject to multiple excitations. Examples were given to demonstrate the application and the efficiency of using the modal contribution indicator to reduce the undesired structural responses
