I thought i’d Got my head around Peters Ballards explanatory write up on GoMoG. Now thanks to this thread I am not so sure.
The bit I don’t get is that he states the two springs (main spring and rebound spring) are in series so the initial total stiffness is the addition of both spring rates. As I see it, since only one spring is compressed when the axel block is moved by a bump this is not the case? Surely the main spring compression is initially aided by the (partly compressed) rebound spring so it effectively reduces the stiffness of the main spring and “softening” the bump effect?
