Suspension Geometry - Compare Suspensions

[ Home ] [ Up ] [ Compare Suspensions ] [ Roll Center ] [ 3D View ] [ Iterative Computations ] [ Editing ] [ Fixture feature ] [ Setup Analysis ] [ Premier Version ]

The WinGeo3 Suspension Geometry program can also compare suspensions in the same manner.  In this example two suspensions are compared. These suspensions are identical except the second has a longer upper A-arm that provides a stable roll center as the vehicle rolls.  This is best displayed in the vehicle frame-of-reference.

In this example the vehicle has rolled two degrees and dropped one inch below the normal ride height.  The right front camber is 0.774 degrees for the first suspension and 0.555 for the second.  But there is a huge difference in roll center movement.  The first suspension has a roll center 25.743 inches left of center.  The second roll center moved only 2.545 inches.  This capability permits rapid analysis of a pair of suspensions and clearly demonstrates the differences between the two suspensions.
