Adding external vibration to a dynamic analysis

I am trying to simulate an experiment in which a steel plate is excited using sound vibration to measure its natural frequencies and vibration patterns. Even if modal frequency analysis of the test gave results, it was not satisfactory. Therefore, the external vibration with a controlled frequency is required to be included in the FEA model. FYI, gravity load will also be considered.

I would appreciate any help, specially related to ABAQUS. If there is no way of doing this in ABAQUS, suggestion of any other FEA software would be fine.

Thanks in advance.
