摘　　要：针对输电线路跨越架在复杂环境载荷作用下的动态响应进行深入分析,通过建立精细化的有限元模型,模拟跨越架在风载、地震及温度变化等多因素耦合作用下的动力学行为。文章首先验证模型的准确性,随后开展一系列数值模拟实验,详细探讨不同载荷条件下跨越架的应力分布、变形特性及振动响应。结果表明,风载是引起跨越架动态响应的主要因素,而地震作用对其影响则呈现出局部性和瞬时性。通过对比分析,提出优化跨越架结构设计的建议措施,以增强其抵抗外部载荷的能力,进而保障电力系统的稳定运行。This paper presents an in-depth analysis of the dynamic response of transmission line span frames under complex environmental loads.A detailed finite element model was developed to simulate the dynamic behavior of span frames under the combined effects of wind loads,seismic activity,and temperature variations.Initially,the accuracy of the model was validated through comparison with experimental data.Subsequently,a series of numerical simulations were conducted to examine the stress distribution,deformation characteristics,and vibration responses of span frames under various loading conditions.The results indicate that wind loads are the primary factor influencing the dynamic response of span frames,whereas seismic effects are localized and transient.Comparative analysis revealed several strategies for optimizing the structural design of span frames to improve their resistance to external loads,thereby ensuring the stability and reliability of power systems.
