摘要:
应用一维有限元方法进行注塑成型过程中温度场的计算机模拟,讨论采用模腔表面平均温度边界条件对传热分析造成的误差.结果显示,当对模具的精度要求不高时,误差是可以接受的;但对于精密注塑件,或者制件很薄,这种误差则会对数值分析产生影响.针对这种情况,根据实际的瞬态温度分布,提出一种用平均温度构造近似的瞬态温度场方法,以提高注塑数值模拟的精度.
Abstract:
The one-dimensional finite element method was used to simulate the temperature field in the injection molding process, and the error caused by the average temperature boundary condition of the mold cavity surface was discussed for the heat transfer analysis. The results show that when the accuracy of the mold is not high, the error is acceptable; However, for precision injection molded parts, or thin parts, this error can have an impact on the numerical analysis. In view of this situation, according to the actual transient temperature distribution, a transient temperature field method with average temperature construction is proposed to improve the accuracy of numerical simulation of injection molding.
