摘要
为解决在超高精度光学加工过程中环境温度分布不均匀,温度场变化过快造成材料热胀冷缩的问题,文中根据热力学基本定律,运用FLUENT软件,通过温度场叠加的基本原理,在FLUENT软件中建立仿真模型,并对溴钨灯的温度场进行数值仿真计算。根据仿真分析,不断优化溴钨灯个数和排列情况,从而得到不同的温度场仿真图形。仿真结果表明,可得到一个较大区域的理想温度场,并在实际运用中得到了切实的验证。
In order to solve the problem in the ultra - high precision optical processing of the environment tem- perature distribution is not uniform, and the material of heat bilges cold shink by the temperature field changed too fast. According to the laws of thermodynamics, and using the FLUENT software, through the principle of superposi- tion of the temperature field, in fluent software established simulation models, And the temperature field of the bro- mine tungsten lamp by numerical simulation. According to the simulation analysis, constantly optimize the bromine tungsten lamp number and arrangement, then the simulation results of different temperature fields are obtained. The simulation results show that the obtained temperature field in a large area,which has been effectively verified in prac- tical application.
