摘　　要：利用ANSYS软件对圆柱薄壁夹具磨削的温度场进行有限元仿真,基于磨削加工的基本原理,建立了合理的假设和热传导数学模型。基于薄壁套筒符合的二维热传导数学模型,在ANSYS中施加边界条件和载荷,得出了圆柱薄壁套内部温度场云图,找到温度最值,对磨削过程温度的变化情况进行分析。根据温度场中的温度分布情况,在加工过程中,合理、有效地安排加工工序,可以极大提高加工精度和效率,同时也为解决圆柱内孔磨削表面热损伤和热变形等问题提供了理论依据。The temperature field of cylindrical thin-wall fixture grinding was simulated by ANSYS software.Based on the basic principle of grinding,reasonable assumption and mathematical model of heat conduction were established.Based on the two-dimensional heat conduction mathematical model of the thin-walled sleeve,the boundary conditions and loads were applied in ANSYS to obtain the temperature field netograph inside the cylindrical thin-walled sleeve,find the maximum temperature value,and analyze the temperature changes during grinding process.According to the temperature distribution in the temperature field,reasonable and effective machining procedures can greatly improve the machining accuracy and efficiency,and also provide a theoretical basis for solving the surface thermal damage and thermal deformation of cylindrical inner hole grinding.
