I've added a photo that it can describe all of things I need to expalin, a Skid, settlement of motor, settlement of a pump or air-end. According to the Din 4024 for the machine foundation, I have to check the possibiloty of vibration on bearings, so I am going to make a dynamic analysis. I think, we can use 2 ways to implement this simulation: control displacement or control force. I want to know that the my way in simulation is correct or not.
I'll be glad if you can help me to solve and even if I am eager to publish this issue as a conference papaer if you are interested in.
