| Abstract: | Structural dynamics modification with targets of random responses for a vibration system is a complex and practical problem. In this paper,accelerations of the structure are used as targets and its displecements are taken as constrains. Thus, fast structural dynamics modification for a large mobile electronic shelter is carried out by means of matrix perturbation and sensitivity analysis. |
