滚珠丝杠-螺母副结合部轴向动态特性参数测试与分析

摘要/Abstract

摘要： 为了获得滚珠丝杠-螺母副结合面轴向动态特性参数，建立了滚珠丝杠-螺母副滚动结合面轴向动力学参数识别模型并研发了测试平台，分析了不同丝杠结构尺寸参数对丝杠轴向动态刚度的影响规律。实验结果表明，丝杠直径、导程、螺旋升角、工作圈数的增大均可提高其轴向动态刚度，而丝杠装配过程中的预拉伸所产生的轴向应变量会减小丝杠结合面轴向动态刚度。最后建立了滚珠丝杠-螺母副结合面轴向动态刚度神经网络预测模型，预测结果表明计算刚度与实测值相差不超过8%。

Abstract: In order to get the axial dynamic characteristic parameters of ball screw, a ball screw axial dynamic parameter identification model was established and a test platform was developed. By test the axial dynamic parameters of different screws, the effects of structure parameters on axial dynamic stiffness of ball screws were analyzed herein. The experimental results show that, the increases of screw diameter, lead, helix angle, and effective circle may improve the axial dynamic stiffness. The increases of axial strains which caused by pretensions will reduce the axial dynamic stiffness. Finally, a prediction model of ball screw axial dynamic parameters was established. And the relative errors between predictive stiffness and experimental results are less than 8%.

Key words: ball screw, contact surface, dynamic stiffness, damping
