The Finite Element Analysis of Surface Temperature on Dry Belt Grinding for Titanium Alloys

Abstract

This paper studies the grinding temperature field of dry belt grinding titanium alloys using finite simulation and experiments. A reasonable finite element model of dry belt grinding temperature field is established on the basis of ANSYS. And three kinds of boundary conditions are loaded on the element of a moving line heat source. The corresponding computer program is designed to calculate the temperature field for different grinding parameters, and the experiment results show that the simulated temperature have good agreement with the measuring ones. The model could be utilized to forecast the distribution and variation characteristics of the grinding temperature field under different conditions.

Review on grinding-induced residual stresses in metallic materials

“…2D and 3D thermal source models for predicting grinding temperature A 2D thermal source model is usually suitable for relatively simple workpiece geometries, which assumes that the thermal body studied has an infinite width or the grinding wheel radius is much larger than the length of wheel-workpiece contact zone [207,215,216]. However, if the extra side wall and convective cooling should be considered, the assumption of 2D thermal source model perhaps does not apply any longer.…”

Definition of Temperature Indicators by Modeling the Process of Globoid Toothohoning Depending on the Parameters of the Hone Installation

“…На кафедре «Металлорежущие станки и инструменты» ПНИПУ разработан метод определения характеристик абразивного слоя глобоидного хона и условий обработки при глобоидном зубохонинговании моделированием напряженно-деформированного состояния рабочих поверхностей ротора и глобоидного хона в зоне контакта [5][6][7][8][9][10][11][12][13][14][15]. Это позволяет перейти к исследованиям теплофизических показателей глобоидного зубохонингования в зависимости от параметров установки глобоидного хона [16][17][18][19][20][21][22][23][24].…”
