Best way to classify knocking loads

[Anonymous]

I have a simple beam and I am applying some knocking forces and measure the acceleration by sensors.

I am trying to model this beam and loads to get the deformation can happen.

My question is: What is the best way to define the loads, is it good to define them as body forces?

because of my measurements units from the accelerometers (g or m/sec^2).

Any advice will be appreciated

Hi @Anonymous

If its knocking force then this force is changing with the time then you need to use the time history approach for such this force then you can get the results (deformation and accelerations).

@mustafahesenow Thank you. Actually, you are right, These type of forces are changing with the time so it's better to use time history analysis.

I watched some video about it and I ran my model but unfortunately, the results are (zero). Maybe I miss something
