I've always normalized so that the generalized mass is 1, but the Nastran lesson here (http://www.aerospacengineering.net/?p=2652) mentions that MAX normalization can lead to developing more intuition for what's going on based on the generalized mass. Can anyone explain what generalized mass physically means in more detail? I always thought the normalization of mode shapes was completely arbitrary.
