Quote from: Myst1cPrun3 on February 13, 2020, 10:47:46 pmI have some questions about the rear suspension simulation, and BikeED....
1) on the picture above you've got the rod as the blue triangle, and the rocker as a red, erm, rod.
Is this right? I would assume that the red, rod, is, well the rod, and the rocker is the blue triangle arrangement, that 'rocks' with the suspension movement? (This is also backed up with a quick ebay search, that the parts are actually the other way around)
The second, is that it appears that the parts are not going to where I would like them. Taking the labels from the diagram above, my red linkage, which is the rocker here (but Really the connecting rod) does not attach to the swinging arm as it should, whenever I get it in the right postion, it pings to a different location and the graph of suspension travel goes all over the place. (The linkage (which is the rocker here) can be attached to either the chassis or swinging arm, in real life and this doesn't seem to be possible here)
Motorcycle Dynamics Second Edition by Vittore Cossalter seems to show this on page 149. fig 5-6. The labelled parts on this fig are the ones that directly connect to the chassis, showing that the rocker and rod can connect to either, in a lot of different orientations, so I cannot see why this would not be possible?
One extra little thing relating to the above point, is the suspension I'm working on is a variation of fig 5, the rocker-chassis (also the way it connects, rocker to chassis, not rod) however, the rear suspension (Shock and spring) joins the rocker (triangle piece) at the bottom. When this is introduced BikeED doesn't seem to like it. This may be something I'm doing wrong however.
Any advice would be useful thanks.
