Title:
SPRING CHARACTERISTICS CORRECTION METHOD AND SPRING CHARACTERISTICS CORRECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/087087
Kind Code:
A1
Abstract:
Provided is a method for correcting a spring with high accuracy so that desired spring characteristics can be obtained for the spring. Said method for correcting the spring is such that in the first place, the spring is compressed until an actual measurement line of the "load vs. displacement" relationship intersects with a target line of the "load vs. displacement" relationship, said actual measurement line of the "load vs. displacement" relationship being an actual measurement line obtained by measuring loads and displacements with respect to the spring, and said target line of the "load vs. displacement" relationship being a target line decided on the basis of the "load vs. displacement" characteristics of the spring and the desired characteristics of the spring (S10 - S14); and that in the next place, the spring is expanded so that load decreases along the target line of the "load vs. displacement" relationship (S18).
