Geometry - Compare Suspensions
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.
