摘要
本文运用有限元法,对注塑模具三维非稳态温度场进行了计算机辅助的数值模拟求解。以曲边六面体二十节点等参数有限单元,推导了有限元数值求解方程并研制了计算机模拟软件。实例计算结果,验证了数值求解的可靠性。
Three-dimensional unsteady temperature distributions of injection mould havebeen calculated by Finite Element Method(F.E.M.).The equations of F.E.M.with 20 noted solid isoparametric element have been deduced.The F.E.M.numerical simulation has been programmed by FORTRAN 77.It wasshowed that the result of the numerical simulation coincided with those of thetheoretical calculation and the computing programm is suitable for practice.
