modal analysis with accelerations

[EracleCafeo]

Hello everyone,
would someone know how to tell me if it is possible to perform a modal analysis in ansys workbench by imposing, beyond frequencies and constraints, a value of acceleration with synoidal trend between zero and a maximum in time?

I must verify that the vibrations and accelerations to which a statue is subjected, very precious, during transport (typically around 2hz and 0.4 m/s^2 for air transport and rubber) do not break it.

Hi.
modal analysis is used to calculate frequencies and ways of vibrating, so it must be done without applied loads.
the analysis you say is a harmonic analysis that allows you to calculate the response of the system to a sinusoidal load (an example brushed in frequency of an acceleration).
in ansys you can do first a modal analysis of which you exploit the solution to do harmonic analysis (resolve the equation of the motion by calculating the movements as a combination of the ways of vibrating).
