基于温升引起静压轴承变形的冷却结构优化仿真
|
摘要
针对某立式机床静压轴承,计算了其内部油膜的温度场及导致的变形,并进行了静压轴承冷却结构的探讨和研究。仿真结果表明:铺设不同数量和不同管径的冷却管,对油膜表面最高温度影响不大,但与不铺设冷却管相比具备较好的冷却效果。研究成果为后续解决立式机床静压轴承温度所引起的变形问题以及冷却结构的优化提供了理论依据。
The temperature field of oil film and induced deformation of vertical machine tool static bearing were calculated, and the cooling structure of the static bearing was discussed and studied. The simulation results show that, the cooling tube with different number and different diameter has little influence on the maximum temperature of oil film, but it has better cooling effect than that without cooling tube. The research results provide a theoretical basis for further solving the deformation problem caused by temperature of vertical machine tool static bearing and the optimization of cooling structure.
