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。

Abstract:

: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.
