摘　　要：复合材料抽油杆横向振动固有频率是影响有杆抽油系统行为的一个重要因素,为减少抽油杆横向振动对抽油杆动态性能的影响,提高复合材料抽油杆使用寿命,采用振动理论和数值模拟相结合的方法,推导了复合材料抽油杆横向振动方程,建立了复合材料抽油杆数值模型,获得了抽油杆前八阶固有频率和振型,为复合材料抽油杆合理结构设计提供理论依据。Natural frequency of composite material sucker rod lateral vibration is one of the most important effect factors of sucker system behavior. To decrease thus influence, and increase service life of composite material sucker rod, this article uses compose of vibration theory and numerical simulation. What＇ s more, we derive the equation of composite material sucker rod lateral vibration, and establish numerical model of it. In the end, we get the first eight steps natural frequency and vibration mode of composite material sucker rod, which provides theoretical basis for reasonable structure design of composite material sucker rod.
