        摘 要:針對特高壓串補平臺結構系統設計需滿足抗震穩定性要求,建立了基于剛柔耦合多體動力學模型,得到平臺整體固有頻率和振型,并在模態分析基礎上,研究了頻域范圍內不同設計變量對系統幅頻響應函數的影響。結合標準地震時程波激勵,計算系統加速度響應以及支柱絕緣子、斜拉桿件載荷力變化特性,對平臺進行時域抗震響應分析。以降低相對位移和加速度為目標進行系統參數優化設計,結果表明:提升阻尼彈簧剛度與斜拉桿件預緊力有利于提升系統的動力學特性,相比初始設計,位移與加速度響應降低了19%。

        Abstract: This paper established a multi-body dynamic model based on the rigid-flexible coupling to meet seismic stability requirementsin the structural system design of the UHV series compensation platform. It helped to obtain the overall natural frequency and mode shape of the platform. This paper studied the influence of different design variables in the frequency domain on the system's amplitude-frequency response function based on model analysis. This model combined the standard seismic time history wave excitation, the acceleration response of the system, supporting insulator, the variation characteristics of loading force of tension diagonal to analyze the time-domain seismic response of the platform. This study optimized parameters for reducing relative displacement and acceleration. The results show that improving the damping of spring stiffness and the pre-tightening force of tension diagonal is beneficial to the dynamic properties promotion. Compared with the initial design, the displacement and acceleration response are reduced by 19%.
        Key words: series compensation platform; seismic response; dynamic characteristics; system parameter optimization
