Disclosed is a test method for determining the relationship between influencing factors of spring performance. First of all, pads of different thicknesses are bonded on the outer side surface of a wedge-shaped structure support ring of the same spring to increase the height of the spring. Similarly, pads of different thicknesses are bonded on the inner side surface of the wedge-shaped structure support ring of the same spring to reduce the clearance of the spring, In the foregoing manner, the height or clearance of the spring can be adjusted insofar as other factors or conditions of the spring are kept unchanged, thereby testing the influences on changes to the height of the spring under a given load. In the present invention, the operation of only changing the size of the clearance or the height by means of bonding or filling is extremely simple, and other unadjusted factors can be guaranteed to be consistent with original factors, thereby achieving the purpose of changing only one of several factors on the same spring, and improving the accuracy of the testing results.
