In this article you will learn how to define a time/frequency dependent excitation load.
- Define the force load from the Analysis ribbon by selecting Loads and Constraints > Force and Moment.
- Define the excitation load from the Analysis ribbon by selecting Loads and Constraint > Excitation.
- You will then link the amplitude table and Force load as shown below.
The “Frequency – Amplitude” table is a generic table format.
Based on the analysis type, it will be treated as “Freq vs Amp” or “Time vs Amp”.
For the Transient modal analysis: It is treated as time-based and written out
TLOAD1 – TABLED1 (Time-based).
For the Modal frequency analysis: It's treated as frequency-based and written out
RLOAD1 -TABLED1 (Freq based)
For the Non-Linear Transient analysis: There is no need to link the loads with the dynamic table through the Excitation load. Loads (Pressure, Force, Enforce constrain) with the Amplitude table will export DLOAD and TLOAD1.
