| 摘 要： | 讨论了粒子群算法(PSO)的应用,并基于PSO算法结合重庆干溪沟1号特大斜拉桥的带减振器的斜拉索做参数识别。研究表明:若拉索多阶振动频率能够被获得,则通过PSO算法得到的T,EI,K,εL等拉索参数是可靠的。 |
| 关 键 词： | PSO算法 减振器 参数识别 斜拉桥 |

| Abstract: | The application of particle swarm optimization algorithm(PSO) is discussed,and the parameter identification of Chongqing Ganxigou No.1 cable-stayed bridge with the shock absorber of cables is carried out,which is based on the PSO algorithm.As was discovered by this research,once the frequency of multiple-order vibration is known,cable indexes calculated by PSO algorithm such as T,EI,K and εL are reliable. |
| Keywords: | particle swarm optimization algorithm attached damper parametric identification cable-stayed bridge |
