Contents |
SID |
Load set identification number. (Integer > 0) |
JID |
Grid point identification number. (Integer > 0) |
MTYPE |
TRANS or ROT, ignored for revolute and translational joints. |
CVID |
Set identification number of the MBCRV entry that gives the motion vs. time. (Integer > 0) |
INT |
Interpolation type Default = AKIMA (Character: LINEAR, CUBIC, or AKIMA) |
EID |
Set identification number of the MBVAR for the independent variable expression. Default = TIME (Integer > 0 or blank) |
DTYPE |
Motion data type (DIS, VEL or ACC), blank means displacement motion. |
D0 |
Initial displacement, if motion data is of type velocity or acceleration, ignored otherwise. |
V0 |
Initial velocity, if motion data type is acceleration, ignored otherwise. |
1. | Joint motion can only be applied to cylindrical joints (MTYPE = TRANS or ROT), revolute joints (MTYPE = ROT), and translational joints (MTYPE = TRANS). |
2. | The MOTNJC Bulk Data Entry should be selected in the MOTION Subcase Information Section, if it is to be included in the analysis. |
