摘要
在分析纳米氧化锆陶瓷材料加工性能基础上,建立了纳米氧化锆精密磨削温度场理论模型,应用ANSYS软件在不同磨削工况下对三维模型进行仿真分析,结果表明:随着砂轮切入工件,工件的温度急剧上升,然后趋于平缓,在工件表面形成极高的温度梯度,若工件足够长,会存在一个稳定区;随着磨削切深增大,磨削弧区形成局部高温,造成工件的烧伤。
Based on analyaing the machining performance of Nanometer Zirconia Ceramics, its precision grinding temperature field theory model is established. ANSYS software is used for three dimensions model simulation analgze under different operating conditions. This simulation results also indicate that the work- piece peak temperature rises rapidly when grinding wheel first engages with the workpiece and a steadystate region exists if the workpiece is long enough. The temperature of the grinding contact zone is increasing with the depth of grinding rising,which can cause workpiece burned.
