摘　　要：采用谐波合成法模拟脉动风,构建一类带线锥形钢筋混凝土电杆的ANSYS有限元模型,分析电杆在脉动风载荷作用下的有限元模态和动力学瞬态变化。结果表明:12级强脉动风不会与该类电杆发生共振;电杆在埋深1/3处应力最大;风载荷作用使得电杆发生扰动,而带线会加大电杆扰动量;通过电杆末端最大扰动量,可有效判断电杆在不同风力等级下的结构稳定性。Using the harmonic synthesis method to simulate pulsating wind,an ANSYS finite element model of a type of tapered reinforced concrete pole with lines is constructed to analyze the finite element mode and dynamic transient changes of the pole under pulsating wind loads.The results show that strong pulsating wind at level 12 will not resonate with this type of pole.The pole has the highest stress at 1/3 of the buried depth,and the wind load causes disturbance to the pole.The strip line will increase the disturbance of the pole.The maximum disturbance at the end of the pole can effectively determine the structural stability of the pole at different wind speeds.
