超声磨削单颗磨粒磨削温度预测与试验研究
|
摘要
为了解决单颗磨粒磨削下磨削区最高温度无法直接通过试验准确测得的问题,基于超声磨削单颗磨粒磨削力公式以及传热理论,推导超声磨削工艺下的热源强度计算公式,通过有限元软件计算单颗磨粒作用下超声磨削温度场分布以及磨削的最高温度,研究各项磨削参数对单颗磨粒磨削区最高温度的影响.给出一种测量磨削温度的测试方法,在同等磨削参数下,磨削区域平均温度的实测值与仿真结果相差在10%以内,验证了该超声磨削单颗磨粒磨削温度场仿真计算方法的正确性.
In order to solve the problem that the highest temperature in single grit grinding zone could not be directly measured by experiment,based on the formula of the single grit grinding force of ultrasonic-assisted grinding(UAG) and the heat transfer theory,the calculation formula of heat source strength under ultrasonic-assisted grinding was derived,the distribution of ultrasonic grinding single grit grinding temperature field and the highest temperature of grinding through the simulation of finite element softw are were obtained.The influence of grinding parameters on the maximum temperature of grinding zone was studied. A test method was presented for measuring grinding temperature,and the difference between the experiment and the simulation results was less than 10%under the same grinding parameters,which verified the correctness of the simulation method of grinding temperature field of single grit grinding of UAG.
