Bulk Data Entry Defines a frequency-dependent dynamic load of the form $P\left(f\right)=A*B\left(f\right){e}^{i\left(\phi \left(f\right)+\theta -2\pi f\tau \right)}$ for use in frequency response problems.

RLOAD2 (Form 2) can be used when the frequency-dependent dynamic load input is available in magnitude/phase number format.

Definitions

Field Contents SI Unit Example
SID Set identification number. Must be unique for all RLOAD1 and RLOAD2 entries.

No default (Integer > 0)

EXCITEID Identification number of the DAREA, SPCD, FORCEx, MOMENTx, PLOADx, RFORCE, ACCEL, ACCEL1, ACCEL2, or GRAV entry set that defines A.

No default (Integer > 0)

DELAY Defines time delay $\tau$ . If it is a non-zero integer, it represents the identification number of a DELAY Bulk Data Entry that defines $\tau$ . If it is Real, then it directly defines the value of $\tau$ that will be used for all degrees-of-freedom that are excited by this dynamic load entry.

Default = 0 (Integer ≥ 0, or Real)

DPHASE Defines phase $\theta$ in degrees. If it is a non-zero integer, it represents the identification number of a DPHASE Bulk Data Entry that defines $\theta$ . If it is Real, then it directly defines the value of $\theta$ that will be used for all degrees-of-freedom that are excited by this dynamic load entry.

Default = 0 (Integer ≥ 0, or Real)

TB
Integer ≥ 0
Set identification number of the TABLED1, TABLED2, TABLED3, TABLED4 or TABLEG entry that gives $B\left(f\right)$ .
Real
This real value is used for $B\left(f\right)$ for all frequencies.

No default.

TP
Integer ≥ 0
Set identification number of the TABLED1, TABLED2, TABLED3, TABLED4 or TABLEG entry that gives $\phi \left(f\right)$ in degrees.
Real
This real value is used for $\phi \left(f\right)$ for all frequencies.
Blank

Default = 0

TYPE Identifies the type of the dynamic excitation.

Default = 0 (See Comment 4)

2. If any DELAY, DPHASE, or TP fields are blank or zero, the corresponding $\tau$ , $\theta$ , or $\phi \left(f\right)$ will be zero.
