Residual Stress Analysis
analysis is beginning ....
Filling phase: Status: V = Velocity control
P = Pressure control
V/P= Velocity/pressure switch-over

Filling phase results summary :
Maximum injection pressure (at 0.147 s) = 75.5678 MPa
End of filling phase results summary :
Time at the end of filling = 0.1626 s
Total weight = 13.7057 g
Maximum Clamp force - during filling = 11.5500 tonne
提示超出了机器的最大注射率该怎么办?filling control 是由Ram speed profile 控制的

上面的推荐注射率在实际注塑中,注塑机如何设定注一\注二的值,请帮忙讲讲

可以通过计算总体积 stroke:然后根据选择的成型机器的螺杆直径计算填充总的螺杆位置(记得加上流延量)。计算出注塑机的最大螺杆速度。然后根据表上的百分比算出每一段的螺杆位置,与每一段位置对应的螺杆速度speed。填入填充控制的表里(控制方式要选择位置与螺杆速度)。

增加注塑时间应该可以了吧

我用mpi5算的也有,问题是根本就没有超过我选用的注塑机的最大注射速率,他还是出现这个警告。请教高手是怎么回事?
