金属体积成形中摩擦系数的计算

Evaluation of coefficient of friction in bulk metal forming

Soheil Solhjoo

摘要:

本文提出了圆柱形“桶压试验”的上限分析方法。BCT法是一种简单易行的方法,可以通过一个圆柱形试样的镦粗试验来定量测定摩擦系数。通过一系列的有限元法(FEM)模拟来检验该方法,并通过FEM模拟的结果来修改该方法。

英文摘要:

In this study an upper bound analysis for cylindrical "Barrel Compression Test" (BCT) is developed. BCT method is a very simple method which can be utilized in order to evaluate quantitatively the coefficient of friction by means of just one cylindrical specimen in an upsetting test. The method is checked by a series of finite element method (FEM) simulations and by means of the results of FEM simulations the method is modified.
