Field

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.

Comments

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.
