On the conditions that a foundation of rotational coordinate system was set up with a virtual system introduced in,a discriminant is derived for the position of the welding point of solidification layers in the process of twin-roll casting,i.
在建立旋转坐标系和引进虚拟系统条件下,根据傅立叶传热微分方程,建立了双辊铸轧过程中凝固层焊合点位置的判别式K=d-4asη2ω-1arcsin(H/R)+s20+s0,由该式能够推断出凝固层焊合点的位置,即当K=0时,凝固层焊合点位于辊缝之间;当K>0时,凝固层焊合点位于辊缝之上;当K<0时,凝固层焊合点位于辊缝之下。
So this method is especially suitable for virtual system a.
同时,该方法稳定性好,不会导致机械仿真模型的分离,特别适用于虚拟系统及复杂的机电系统。
