摘要
文章以YS3118CNC数控滚齿机的刀架部件为研究对象,对其温度场及热误差进行了仿真分析。应用有限元法,结合热结构耦合技术仿真计算了刀架部件的稳态温度场与热变形,对其稳态时的温度场分布与热变形特点进行分析;采用相同的方法仿真计算了刀架部件的瞬态温度场与热变形,分析其温升特点与热误差动态特性。通过仿真分析得出了数控滚齿机刀架的温度场及热误差特性,得到了其稳态和瞬态时的温度、热误差数据,为数控滚齿机热误差的建模以及补偿打下较好的基础。
The temperature field and thermal error of Y3118CNC hobbing machine turret parts were simulated. Using the finite element method and the thermal structure coupling technology, the steady temperature field and deformation of the turret parts were simulated and the temperature field distri- bution and thermal deformation characteristics were explained. Then, the transient temperature field and deformation of the turret parts were computed and the temperature rising feature and thermal er- ror dynamic properties were analyzed. Through simulation analysis, the temperature field and thermal error characteristics of the turret were obtained, and the temperature and thermal error data in both steady and transient states were acquired. The study lays a good basis for the thermal error modeling and compensation of CNC hobbing machine.
