You should perform some multi-body dynamics simulation prior to choosing your actuators. This could be done in most CAD software like Solidworks, Inventor etc. You can also do it with more specialized tools like ADAMS, RecurDyn, Simmechanics etc.
You may find the attached publications useful. However, they come from different domains in robotics.
