By using the ansys software , a finite element model which simulates a real sls process of a multi - component ni - cusn metal powder system was established to calculate the 3d transient temperature field 利用ansys有限元软件,建立了ni - cusn多组元混合粉末选择性激光烧结过程三维瞬态温度场分析模型。
Based on the results of temperature field , a finite element model for analyzing the stress field in sls process of a multi - component metal powder system was established by using an indirect thermal - mechanical coupling method 基于温度场的计算结果,采用热力耦合方法,建立了ni - cusn多组元混合粉末选择性激光烧结过程应力应变场分析模型。
To alleviate the defects in metallic sls , numerical and experimental studies were carried out detailed on the features of temperature field as well as thermal elastic - plastic stress and strain during metallic sls process 因此,本文针对ni - cu基多组元混合粉末选择性激光烧结温度和应力应变的变化规律和特点开展了系统深入的数值分析和试验研究。
