Attached Pdf is a free boday diagram of a vibratory roller without of balance vibratory mechanism. I need to determine the drum displacement (Xd), frame displacement (Xf) and the phase lags (Teta f and Teta d). where do i need to start from and what softwares can i use?

Hi, I would like to help you, but I don't understand your drawing. However the most simple software to model it, is simechanics.

the problem i have is how to start the initial conditions..i know that the Xd and Xf and their velocities are zero, then the question is how put these into the equations to find the unknown variables!
 
research something called "state space". That should help you a lot.
