摘　　要：对深孔加工中的钻杆-工件模型进行分析,基于高压切削油对钻杆涡动的影响,考虑动压润滑力,建立钻杆-工件数学模型,并对其求解。设计电涡流位移传感器测量钻杆横向位移实验,运用MATLAB对测得的数据进行钻杆中心轨迹及横向位移图绘制。对比系统频率模型计算值与实验测得值,验证了数学模型的准确性,对钻杆系统的涡动控制的研究具有实际意义。In this paper, the model of the drill pipe-workpiece in deep hole machining is analyzed. The mathemati- cal model of the drill pipe-workpiece is established and solved based on the effect of high pressure cut- ting oil on the whirling motion of drill pipe and dynamic pressure lubrication. An experiment is designed to measure the lateral displacement of the drill pipe by the electric eddy current displacement sensor, then the diagram of drill pipe center track and lateral displacement are drawn by MATLAB. By comparing the calculated values with the measured values of the system frequency model, the accuracy of the mathematical model is verified which is of practical significance to the study of the vortex control of the drill pipe system.
