本文的目的是分析GMM作动器在高压输电塔结构中的优化布置方法。方法采用MATLAB软件编写了适应度函数程序,并利用遗传算法工具箱进行了相应的优化计算,编写了LQR控制算法程序,输入EL-Centro地震波,进行了无控结构、受控结构在随机布置和优化布置GMM主动控制系统时的地震响应分析。结果表明,GMM主动控制系统对高压输电塔结构的地震响应控制效果明显,一般情况下,受控结构在优化布置时的地震位移响应可比无控结构的地震位移响应减小35%左右,并且比随机布置时的地震位移控制效果要高20%。本文对高压输电塔结构的动力特性和振动控制进行了研究,得到了一些对实际工程抗震设计具有参考意义的结论。
The purpose of this paper is to analyze the optimal arrangement of the GMM actuator in a high-voltage transmission tower structure. Methods The fitness function program was written by MATLAB software, and the corresponding optimization calculation was made by genetic algorithm toolbox. The program of LQR control algorithm was programmed, the EL-Centro seismic wave was input, and the structure of uncontrolled structure was controlled. Seismic Response Analysis for Optimal Layout of GMM Active Control System. The results show that the GMM active control system has obvious effect on the seismic response control of high voltage transmission towers. Under normal circumstances, the seismic displacement response of the controlled structures can be reduced by about 35% compared with that of uncontrolled structures, and the ratio Earthquake displacement control effect when arranged randomly is 20% higher. In this paper, the dynamic characteristics and vibration control of high-voltage transmission tower are studied, and some conclusions that have reference significance to the actual engineering seismic design are obtained.
