| 摘 要： | 分析了点磨削与普通外圆磨削接触区域的不同,基于热源温度场分布和传热理论,建立了高速点磨削下温度场的理论模型和有限元模型.运用ANSYS对高速点磨削下工件与砂轮接触区域的温度场进行三维仿真,得到了接触区域温度场的分布及温度随时间变化的曲线,总结出最高温度与点磨削变量倾角α的关系,当α不为零时,磨削区域的温度低于普通外圆磨削.通过观测磨削后的工件表面金相组织可知,高速点磨削下仍出现了很薄的磨削变质层,验证了理论分析,为高速点磨削温度场的进一步研究提供了参考依据.

| Abstract: | The contacting area difference between the point grinding and cylindrical grinding was analyzed.Theoretical and finite element models of the temperature field were built based on theories of heat source temperature field distribution and heat transfer.Three dimensional simulation of the temperature field was carried out with the ANSYS software for the contact area between the workpiece and the wheel.Then the distribution of temperature field and the mutative curve of temperature versus time were calculated.... |
