摘　　要：针对防振锤在不同工况下无法发挥最佳防振性能的问题,构建防振锤子系统模型,简化功率特性数据采集方程,设计实验装置对防振锤进行功率特性数值仿真计算,得到防振锤的功率特性曲线,并采用Kriging模型对防振锤的绞线抗弯刚度、绞线股间摩擦系数、材料内阻尼进行动力学优化。模拟实验结果表明:仿真结果与测定结果较为吻合,防振锤的功率特性仿真数值具有可靠性;在不同频率工况下,优化后输电导线的振幅、比振幅较小,说明防振锤功率消耗较大,具有更好的防振性能。In order to solve the problem that the vibration damper cannot give full play to the best anti⁃vibration property under different working conditions,the author constructs the model of the vibration damper subsystem,simplifies the power characteristic data acquisition equation,designs the experimental device was to numerically simulate the power characteristics of the vibration damper,through whith the power characteristic curve of the vibration damper is obtained,and uses the Kriging model is used to dynamically optimize the bending stiffness of the strand,the friction coefficient between strands and the internal damping of the vibration damper.The experimental results show that the simulation results are close to the measured results,and the simulated values of the power characteristics of the vibration damper are reliable.Under different frequency conditions,the amplitude and amplitude ratio of the transmission line is smaller after optimization,which shows that the vibration damper has higher power consumption and better anti⁃vibration property.
