vibrations: how to model a forceful?

[luigi.paiano]

Hello everyone,
Suppose you have a robotic arm and you want to understand what happens when the clamp opens or closes. Usually the answer is calculated by sine-idal buttons, and in this case?so of the transformation of fourier, but it applies only in particular cases.discuss the inexperience.

but you do not have vibrations because the clamp opens or closes, when you go to bite an object with the clamp you have two equal and contrary forces that cancel on the two inner planes of the "ditas", you have transient vibrations when moving the axes, in that case the forces of inertia induce an oscillating movement.

p.s.
I think you say "model" and don't model.

hi luigi, the vibrations are transient but if you think you put this fixed vacuum robot on the ground and to open and close the vacuum pliers you will have a mass moving. if you open and close with a certain range of intervals you will have a function that defines the forcing of the system. if you know the forcing of the system you can calculate the amplitude of the vibration and then control of the drive....see dynamics and control of the mechanical systems that you do at university.

then how simple or difficult it is to calculate the associated homogenea, the particular and to get to define the form of amplyness. You have to see this with some trick.
