[ 旋转轴方向余弦的2分量 ] 3-component of the direction cosine of the axis of rotation. [ 旋转轴方向余弦的3分量 ] 与ABAQUS中需要输入的确定旋转轴的两个点的坐标转换的方法如下所述: 设两个点的坐标分别为(x1,y1,z1)(x2,y2,z2);Column4(1)- Column9(1)分别为a1,b1,c1,a2,b2,c2。 则x1=a1 y1=b1 z1=c1 x2=a1+a2*m y2=b1+b2*m z2=c1+c2*m 其中m=sqrt((a2)^2+(b2)^2+(c2)^2) 比方说Column4(1)- Column9(1)分别为3.5,4.8,2.3,3,4,0,则导入ABAQUS后两个点的坐标分别为(3.5,4.8,2.3)、(18.5,24.8,2.3) 18.5=3.5+3*sqrt(3^2+4^2) 24.8=4.8+4*sqrt(3^2+4^2) 2.3=2.3+0*sqrt(3^2+4^2)
a).如果是Gravity,输入的Column4(1)- Column6(1)三个参数为a1,b1,c1,Magnitude值为Q。它在ABAQUS中的分量大小为分别为Q*a1/m'、Q*b1/m'、Q*c1/m'。其中m'=sqrt((a1)^2+(b1)^2+(c1)^2) b).如果是Centrif,输入Column4(1)- Column9(1)这六个参数,Magnitude值为Q。它在ABAQUS中的分量大小为sqrt(abs(Q)) c).如果是Rota,输入Column4(1)- Column9(1)这六个参数,Magnitude值为Q。它在ABAQUS中的分量大小为Q |
