回答1:

KEYOPT(2)Degree-of-freedom selection for 1-D behavior:
0 -- Use KEYOPT(3) options
1 -- 1-D longitudinal spring-damper (UX degree of freedom)
2 -- 1-D longitudinal spring-damper (UY degree of freedom)
3 -- 1-D longitudinal spring-damper (UZ degree of freedom)
4 -- 1-D Torsional spring-damper (ROTX degree of freedom)
5 -- 1-D Torsional spring-damper (ROTY degree of freedom)
6 -- 1-D Torsional spring-damper (ROTZ degree of freedom)
7 -- Pressure degree of freedom element
8 -- Temperature degree of freedom element

这个是单元的说明中的一向,所以,如果你把关键项2选择为4,5,6等标识数字的话,就是具有扭转了,不过呢,你建立的14单元,一定要是一个你建立单元所在坐标系统相同的,这样,这些数字才是具体的某个方向的轴向或者是扭转弹簧了

当然,如果你的模型是2D或者是3D的,就选择下面的,与上面的类似理解
KEYOPT(3)Degree-of-freedom selection for 2-D and 3-D behavior:
0 -- 3-D longitudinal spring-damper
1 -- 3-D torsional spring-damper 2 --
2-D longitudinal spring-damper (2-D elements must lie in an X-Y plane)
也就是,0就是轴向,1就是扭转了
