摘要
在实验基础上 ,采用幂律粘度模型建立了熔模铸造用模料的流动本构方程 ,将其应用到数值模拟系统中 ,成功地实现了对熔模铸造用模料充型过程的数值模拟。
On the basis of experiment,by using the exponential viscous model,a flow constitution equation of the pattern material(wax stock)used in investment casting has been established.By applying it to the numerical simulation system,the numerical simulation on die filling process of the fusible pattern material(wax stock)used in investment casting has been successfully realized.
