摘　　要：以YK3150E数控滚齿机刀架部件为研究对象,通过对刀架部件的主要热源进行分析,计算出主要热源的发热量,确定了热边界条件,利用ANSYS有限元分析软件对刀架部件进行稳态、瞬态温度场分析和稳态热变形分析,仿真分析结果表明,滚刀在X方向上的热变形量最大,为14.6μm,Y和Z方向上的热变形量都小于10.0μm,热误差变形较小。与试验结果比较,误差小于5%,在允许的误差范围内,可为该型数控滚齿机热误差建模与补偿提供参考。The tool carrier assembly of YK3150 E CNC hobbing machine is taken as the research object. Through the analysis of the main heat source of the tool holder, the heat generation of the main heat source is calculated, and the thermal boundary conditions are determined. Using ANSYS finite element analysis software, the steady-state, transient temperature field analysis and steady-state thermal deformation analysis of the tool holder are carried out. The simulation results show that the thermal deformation of the hob in the X direction is the largest, the deformation is 14.6 μm, and the thermal error deformation in the Y and Z directions is small, the deformation is less than 10.0 μm. Compared with the test, the error is controlled within the allowable error range of 5%, so it can provide a reference for the implementation of thermal error modeling and compensation of hobbing machine.
