【摘要】：低溫沉積成型是一種現(xiàn)代綠色的增材制造技術。在沉積過程中隨著沉積層的增高,冷凍所需要時間也在變化。建立了低溫沉積過程的溫度場模型,運用數(shù)值模擬的方法對沉積過程的溫度變化進行模擬仿真。分析出凝固時間和初始溫度、沉積層數(shù)、環(huán)境溫度和層間等待時間的關系,找到了最短冷凍時間,提高了沉積效率。低溫實驗的結果也證明了模型的正確性。
[Abstract]:Low temperature deposition molding is a modern green material increasing technology. As the deposition increases, the time required for freezing also changes. The temperature field model of low temperature deposition process is established, and the temperature variation of deposition process is simulated by numerical simulation method. The relationship between solidification time and initial temperature, deposition layer number, environment temperature and waiting time between layers was analyzed. The shortest freezing time was found and the deposition efficiency was improved. The results of low temperature experiments also proved the correctness of the model.
