Perhaps a bit of a simple question, but since I don't have a background in robotics/engineering, then I imagine this would be the perfect place to ask such a question.
I am buying a 6-DOF Stewart platform to perform an experiment. In this experiment, I will impose to the device (a small ship) that is attached to the platform (it will be something similar to the one on the picture attached) a harmonic motion over two degrees of freedom, in my case, it will be along the x-axis (surge) and along the y rotating axis (pitch). So that is, I want my device to go back and forth in a given frequency for a defined amplitude.
My question is: Given that I know the FREQUENCIES and the AMPLITUDES that I want to perform on my experiment as well as the WEIGHT of my ship. Then, how could I calculate the specifications needed to specify what would be required by the platform (in terms of forces and motion)?
