[求助] 齿轮ANSYS IS-DYNA分析载荷加载

求助各位虫友，麻烦大家解答一下！
我在做齿轮ANSYS IS-DYNA分析时（一般直齿），将齿轮内圈定义为刚体，其余的齿轮为弹性体，刚体的材料定义时，限制了X/Y/Z的平动自由度和X/Y的旋转自由度
用命令流定义了局部坐标
edlcs,add,11,0.5,0,0,0.5,0.10,0,0,0,0
edlcs,add,12,0.5,0,0,0.5,0.10,0,0,0.1,0。
用以下命令定义载荷：
*dim,time,array,3,1,1
*set,time(1,1,1),0
*set,time(2,1,1),0.001
*set,time(3,1,1),0.050

*dim,vel,array,3,1,1
*set,vel(1,1,1),0
*set,vel(2,1,1),50
*set,vel(3,1,1),50

*dim,torque,array,3,1,1
*set,torque(1,1,1),0
*set,torque(2,1,1),376
*set,torque(3,1,1),376
用以下命令定义接触和加载
edcgen,asts,2,1,0.2,0.1,0,0,0, , , , ,0,1e21,0,0
edload,add,rboz,11,3,time,vel,,,,, ！定义绕Z轴的转速
edload,add,rbmz,12,4,time,torque,,,,, ！定义绕Z轴的转矩

但是在求解时，不成功在MESSAGE文件中提示
   the y-rotational degree of freedom of rigid body 3  is restrained but has a velocity boundary condition applied. The velocity will be set to zero.

   slave surface of interface =       1
   type                      =    a 3
   surface timestep          = 7.493E-08
   controlling slave node ID =    5081
   part ID of slave node       =       1
   current minimum time step = 7.493E-08

   master surface of interface  =       1
   type                      =    a 3
   surface timestep          = 6.901E-08
   controlling master node ID =    95022
   part ID of master node    =       2
   current minimum time step = 6.901E-08

提示说给Y轴施加了转速，我就是不明白为什么Y轴有速度，明明不是给Z轴施加了转速了吗？

希望虫友给解释一下！
