dig into the lesson in the motion manual about importing motion loads into solidworks simulation or the similar lesson in the simulation training.
basically it describes how a single frame or a couple of frames can be imported and that only really the inertial loads are imported. so that isn't going to work for you.
what you'll want to look at is nonlinear dynamic analysis in solidworks premium. this is going to be a pretty complicated analysis so make sure you really can't get away with the motion simulation first. ie that your deformations are very important to the analysis.
Jared, Thank you very much for your answer and advice.
I will check carefully the motion study and also check whether I can get away with this motion simulation.
