建议采用direct法:
*STEADY STATE DYNAMICS, DIRECT
这样就不用求解模态。
多看帮助文件:
An amplitude definition can be used to specify the amplitude of a load as a function of frequency (“Amplitude curves,” Section 30.1.2).
Input File Usage: Use both of the following options:
*AMPLITUDE, NAME=name
*CLOAD or *DLOAD, REAL or IMAGINARY, AMPLITUDE=name
Abaqus/CAE Usage: Load or Interaction module: Create Amplitude: Name: name
Load module: load editor: real (in-phase) part + imaginary (out-of-phase) part i: Amplitude: name
