基于Archard模型的机床导轨磨损模型及有限元分析
|
摘要
机床导轨的磨损是导致机床精度降低或丧失的重要因素。针对机床导轨磨损深度的预测问题,提出了一种基于Archard模型与有限元模拟试验的机床导轨磨损分析方法。该方法基于修正的Archard模型形成一种磨损深度的计算公式,并采用一种离散化计算方法进行求解;结合ANSYS软件,提出机床导轨磨损有限元分析模拟的方法及流程;最后,以车床滑动导轨为例,用有限元试验方法对机床导轨的磨损过程进行模拟分析,得到磨损深度关于磨损次数的计算公式,其结果表明:机床导轨磨损深度的仿真模拟值与实际值具有一致性。
The wear of Machine Tool is the important factors which result in machine precision decrease or loss.In view of wear depth prediction of machine tool,a method of machine tool wear analysis based on Archard model and finite element simulation experiments is proposed.The method based on modified Archard model to form a kind of wear depth calculation formula,and adopts a discretization method to solve;with the ANSYS software,machine tool wear finite element analysis simulation methods and processes are mentioned;Finally,using lathe sliding guide as an example,an experiment using the finite element method is done to simulate and analyze the wear process of the slideway of machine tool,and a formula of wear depth about the number of wear is obtained.The results show that the simulation values of machine tool wear depth is consistent with the actual values.
