| Abstract: | The problems of dynamic response analysis of closed loop control system based on reliability for the intelligent truss structures with random parameters were studied in this paper. Considering the randomness of physical parameters of structural material and applied loads and control forces, the computational expressions of numerical characteristics of closed loop control system of structural dynamic response were derived by means of the mode summation method. The influences of the randomness of physical parameters of structural material and the amplitude of loads and the control forces on structural dynamic response were studied through engineering examples and some useful conclusions are obtained. |
