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！ 另附K文件内容： $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $ COORDINATE SYSTEMS $ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $ *DEFINE_COORDINATE_VECTOR 11 0.5000 0.0000 0.0000 0.5000 0.1000 0.0000 *DEFINE_COORDINATE_SYSTEM 12 0.0000 0.1000 0.0000 0.5000 0.0000 0.0000 0.5000 0.1000 0.0000 $ $ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $ LOAD DEFINITIONS $ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $ $ $ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $ RIGID BOUNDRIES $ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $ *DEFINE_VECTOR 11 0.5000 0.0000 0.0000 0.5000 0.1000 0.0000 *DEFINE_CURVE 1 0 1.000 1.000 0.000 0.000 0.000000000000E+00 0.000000000000E+00 1.000000000000E-03 5.000000000000E+01 5.000000000000E-02 5.000000000000E+01 *BOUNDARY_PRESCRIBED_MOTION_RIGID 3 8 0 1 1.000 11 0.000 0.000 $ *DEFINE_CURVE 2 0 1.000 1.000 0.000 0.000 0.000000000000E+00 0.000000000000E+00 1.000000000000E-03 3.760000000000E+02 5.000000000000E-02 3.760000000000E+02 *LOAD_RIGID_BODY 4 7 2 1.000 12 0 0 0 $ $ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $ CONTACT DEFINITIONS $ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $ *CONTACT_AUTOMATIC_SURFACE_TO_SURFACE 1 2 3 3 0 0 0 0 0.2000 0.1000 0.000 0.000 0.000 0 0.000 0.1000E+08 1.000 1.000 0.000 0.000 1.000 1.000 1.000 1.000 $ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $ CONTROL OPTIONS $ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $ *CONTROL_ENERGY 2 2 2 2 *CONTROL_SHELL 20.0 1 -1 1 2 2 1 *CONTROL_TIMESTEP 0.0000 0.9000 0 0.00 0.00 *CONTROL_TERMINATION 0.300E-01 0 0.00000 0.00000 0.00000 *DATABASE_HISTORY_NODE 1 $ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $ TIME HISTORY $ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $ *DATABASE_RCFORC 0.3000E-03 *DATABASE_MATSUM 0.3000E-03 *DATABASE_BINARY_D3PLOT 0.3000E-03 *DATABASE_BINARY_D3THDT 0.3000E-03 *DATABASE_BINARY_D3DUMP 2825570 $ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $ DATABASE OPTIONS $ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $ *DATABASE_EXTENT_BINARY 0 0 3 1 0 0 0 0 0 0 4 0 0 0 *END |
