摘要
采用遗传算法导出了扰流防舞器的空气动力特性表达函数 ,在加装扰流防舞器后 ,通过改变其系统的空气动力特性 ,可以有效地抑制舞动现象的发生。该算法较大地提高了导线起舞的临界风速 ,具有较为明显的防舞效果 ,为这种新型防舞器提供了计算依据 ,并验证了其防舞效果。
The harmful galloping of iced overhead power lines will arise under given wind excitations. After an anti-galloping spoiler has been installed, the galloping phenomenon is effectly suppressed due to the change of aerodynamic behavior of the system. In this paper, a formula for expressing the aerodynamic behavior of the spoilor has been derived by genetic algorithm, which forms the basis for the calculation of the spoilor and its effectiveness of anti-golloping is proved by the calculations.
