Suspension motion analysis

Posted by Bob Dold on Monday, September 25, 2006 10:20 PM

Created a motion model using CosmosMotion software to predict loading on shocks throught the suspension travel. The plot below shows the loading on the front shock vs. the shock travel, the nominal shock position is at .5 inches.

The plot below is the loading on the rear shock from the swingarm:

In both cases the load increases near the end of the travel due to the mechanical advantage of the linkage. The applied wheel load is 1G in the vertical direction.
