【摘要】 简单介绍了一下有限元计算软件的建模过程,并对在不同切削速度下,硬质合金刀具切削钛合金的过程进行了模拟,得到了切削过程中刀具上应力场和温度场的分布状况。通过对模拟结果的分析与研究,得到了刀具最易出现的磨损区域,并通过与试验结果相对照,证明了有限元模拟方法的可行性,其模拟结果可以为试验提供一定的指导。更多还原

【Abstract】 This paper simply introduces the process of the finite element software modeling.By using this software,the process of cemented carbide tools cutting titanium under different speed is simulated.And the parameters of cutting force and the temperature field,stress field on the tools ect.are achieved.Through studying on the simulation results,regions of tool which are likely to be worn are obtained.From comparing the results of the stimulation,it proves that the method of finite element simulation is feasible,and provides some guidance for the tests by the simulation results.更多还原
