Please see attached example. Force excitation is not supported in Mechanical interface and command snippets have to be used in Mechanical. The procedure is well explained in ANSYS Help: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v191/ans_str/Hlp_G_STR6_8.html?q=Performing%20a%20Random%20Vibration%20(PSD)%20Analysis

- Why is damped frequency is lower than undamped frequency with viscous damping but larger with structural damping?
- How can I change the normalization method of the vibration modes from modal analysis?
- Why does the prestress from Static analysis does not add up to the stress in Random Vibration analysis?
- A Shock absorber is represented as spring element with damping constant. Modal analysis is performed using Reduced Damped (QRDAMP) solver. How to perform a Modal super position harmonic or transient analysis further ?
- In the results of a modal analysis, how can I define that a frequency is an output parameter ?
- What does the warning “Diagonal of the mass matrix is missing in file” indicate when using RSTMAC command?
- Can you output the frequency response for a total deformation?
- What is mass moment of inertia in Point Mass used for?
- In a Modal Analysis of Mechanical, why aren’t the Participation Factors Summary under Solution Information displayed?
- If the stress is higher than ultimate strength in Response Spectrum Analysis, does this mean that the component may break or yield?
