Hello,
I am a bit confused with the answer is transient analysis. When I apply 1g, 30 Hz and 1g, 100Hz vibration separately, I am getting higher displacement (total) for 30 Hz, not for 100 Hz. The reason is if I convert the acceleration to displacement, then it becomes 9.8/(2*pi*f)^2. So increasing f, increase the displacement that is going to be applied to the structure, therefore, it results in lower total displacement (after simulation) for 100 Hz. Is it normal?
