摘要：
The final manufacturing performances of the machine tools will be influenced by its thermal characteristics seriously and accurately predict thermal characteristic is helpful to improve the machine design level. Based on the analysis on factors that influence machine thermal characteristic, finite element analysis model of the headstock has been constructed, and the steady temperature field distribution and thermal equilibrium time calculation of the headstock are calculated, and then the temperature field and thermal deformation of the headstock under the action of heat and structure load have been calculated, and analysis to identify the trend of the spindle assembly and headstock heat distortion are also been done. The analysis reveals the machine processing performance influence will be influenced by the hot asymmetric, the study give priority to spindle assembly of optimization design, thermal error compensation.
