| Abstract: |
| Based on more reasonable assumption that unknown external forces vary linearly within the discrete time interval, an improved method for dynamic load identification for proportional damping system was presented. A set of concise recursive formulae for determining the values of these forces was derived, any one of structural response: displacement, velocity or acceleration needed only for the input. Practical examples showed that compared with other formulae given in recent literature, the proposed approach is simple, effective and has a strong anti-noise ability. |
