Axial Dynamic Stiffness Identification and Analysis of Ball Screw
摘要
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 dy-namic 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 be-tween predictive stiffness and experimental results are less than 8%.关键词
