  I already done impulse hammer test using FFT analyzer and now i'm trying to simulate it using ansys Transient Structural, in the setting for Force, can i just put -150N or there is equation if im trying to copy the force of impulse hammer in Ansys Simulation? -Thank you

  the force in Ansys mechanical can be defined as Constant, Tabular and Time Varying. Thus you can define the -150N as an equation or in a tabular form as per requirement.
  You can refer to the following resources for detailed information regarding the same-
  Force (ansys.com)
  Defining Boundary Condition Magnitude (ansys.com)

  thanks you for the reply it seems that i cant open the link that u`ve given. I dont know how to simulate impulse hammer, impulsive force from the experimental modal analysis like trying to imitate the same froce-time data such as shown in FRF data.
  Thanks Hajid

  I am trying to imitate this kind of impulse force from experimental modal analysis FRF data to simulate it in Ansys Analysis

  The following steps mat help you generate the similar response as the input to your analysis.
  Define the appropriate number of steps, step end time, initial time step, maximum and minimum, etc. (This does divides your analysis as per your input steps)
  Then insert the Force and define the force using the tabular data. Click on the graph menu to see the response of the input defined.
  Add the other boundary conditions and the outputs and solve the example.
  Note- Defining the Analysis settings is the most critical step for Transient analysis as many factors are involved like your hardware capacity, your expected accuracy and the steps required to define the boundary conditions.
  
  You can refer to the following links for detailed information -

  Hope that helps!
