Abstract:
A spring testing system comprising:first and second compression plates each having a pattern of sets of holes, wherein the holes in each set of holes in the first and second compression plate are distributed such that the holes of each respective set of holes in the first compression plate are equi-distributed around a center point on the first compression plate and aligned with a corresponding hole on the second compression plate, and wherein all holes in a first set have a first uniform distance from the center on the first compression plate, and wherein all holes in a second set have a second uniform distance from the center on the first compression plate, wherein the second uniform distance is larger than the first uniform distance;a set of containment rods which pass through the sets of holes in the first and second compression plates to form cage having adjustable dimensions to surround a spring under test and prevent its escape during testing, wherein said set of containment rods comprise five containment rods that are equi-distributed about the spring, wherein the containment rods are fixed to the first compression plate, and pass through the holes in the second compression plate,a means to secure the containment rods; a means for compressing the compression plates; anda means for measuring the performance of the spring under test.
