    • Abstract
  • In order to solve the dynamic optimization problem of transmission tower,a dynamic topology method based on Precise Time-Integration is presented.According to the balanced equation of a tower forced by the simulated wind load,the vibration response of an ultra-high voltage transmission tower is calculated by the precise time-integration.The topology optimization is based on adaptive genetic algorithms (AGA) with the oscillation responses as its constraints.And the topology optimization is composed of topology configuration,shape and section optimization.Considering the coupling of topology,shape and section,adaptive genetic algorithms are used to seek the optimal objective by programming with the MATLAB.The optimization results show that the presented method reduces the structural weight and is obviously better.Dynamic topology optimization method guarantees the safety of the ultra-high voltage transmission tower as well as a visible reduction of its cost.
