摘要
从理论上详细分析了螺杆钻具与螺杆泵中挠性轴的动态问题。借助于加权残数法获得了挠性轴的自振频率及动力学失稳条件，从而为挠性轴的结构设计及工作参数选择提供理论依据。
This paper analyzes the dynamic problem of flexible axle relvant to screw drill tool andscrew pump,obtains the self-oscillation frequency and dynamic unstability conditions bymeans of the Calerkin method,and provides the theoretical basis for structure design andwork parameter selection of a flexible axle.
