Abstract
The invention discloses a test method for judging the relationship of spring performance influence factors, which is characterized in that firstly, gaskets with different thicknesses are stuck on the outer side surface of a wedge-shaped structure supporting ring of the same spring to increase the height of the spring; similarly, the inner side surface of the supporting ring with the wedge-shaped structure of the same spring is adhered with gaskets with different thicknesses to reduce the gap of the spring, so that the height or the gap of the spring can be adjusted under the condition that other factors or conditions of the spring are not changed, and the test of influencing the height change of the spring under given load is realized. The invention has the advantages that the operation of only changing the size or height of the gap in a sticking or filling mode is extremely simple and convenient, and other factors which are not adjusted can be ensured to be consistent with the original factors, so that the aim of only changing one of the factors on the same spring is fulfilled, and the accuracy of a test result is improved.
Description
Technical Field
The invention relates to a test method for judging the influence factor relationship of spring performance, belonging to the technical field of spring tests.
Background
The effect of spring clearance size and height increase on the height of a spring at a given load is typically tested by measuring various spring-related parameters, and summarizing and analyzing the results. The biggest disadvantages of the method are that: the height under a given load is influenced by a plurality of factors (such as gap size, rigidity size and height change), the influence of other factors cannot be excluded in the test, the other factors or conditions can only be assumed to be unchanged in the practical analysis, but the factors above different springs in the practical test are different (namely are changed at the same time). In the prior art, one factor is changed by reproducing a sample piece, but other factors are difficult to be ensured to be consistent with the original factors; one factor of changing is also achieved by re-producing the specimen pieces to adjust the gap or height, but this operation is very complicated and it is difficult to ensure that the other factors that are not adjusted are consistent with the original ones. Therefore, other factors or conditions assumed are hardly possible without change, resulting in an inaccurate test result.
Disclosure of Invention
The invention aims to provide a test method for judging the influence factor relationship of spring performance, which is simple to operate, reliable in test result and capable of improving test efficiency, so as to overcome the defects in the prior art.
The technical scheme of the invention is as follows: a test method for judging the influence factor relationship of spring performance comprises the steps of firstly, sticking gaskets with different thicknesses on the outer side surfaces of supporting rings with the same spring wedge-shaped structure to increase the height of a spring; similarly, the inner side surface of the supporting ring with the wedge-shaped structure of the same spring is adhered with gaskets with different thicknesses to reduce the gap of the spring, so that the height or the gap of the spring can be adjusted under the condition that other factors or conditions of the spring are not changed, and the test of the relationship of performance influence factors on the same spring is realized.
Further, the thickness of gasket is 1 ~ 5 mm.
Due to the adoption of the technical scheme, the invention has the advantages that: the invention has the advantages that the operation of only changing the gap size or height of the spring in a sticking or filling mode is extremely simple and convenient, and other unadjusted factors can be ensured to be consistent with the original ones, so that the aim of only changing one of the factors on the same spring is achieved, the problem that only one of the three factors of the gap size of two ends of the spring, the rigidity of the spring and the height of the spring can not be changed is solved, the three factors form a one-to-one correspondence relationship with the height under the given load, and the accuracy of the test result is improved.

FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and examples.
The embodiment of the invention comprises the following steps: referring to fig. 1, the test method for determining the relationship of the spring performance influencing factors of the present invention includes firstly, adhering spacers with different thicknesses on the outer side surface 1 of the wedge-shaped structure supporting ring of the same spring to increase the height of the spring; similarly, the spacers with different thicknesses are adhered to the inner side surface 2 of the supporting ring with the wedge-shaped structure of the same spring to reduce the gap of the spring, so that the height or the gap of the spring can be adjusted under the condition that other factors or conditions of the spring are not changed, and the test for influencing the height change of the spring under given load is realized. The thickness of the gasket is 1-5 mm.
In conclusion, the operation of only changing the size or height of the gap in a pasting or filling mode is extremely simple and convenient, and other unadjustable factors can be ensured to be consistent with the original ones, so that the aim of only changing one of the factors on the same spring is fulfilled, the problem that only one of the three factors of the size of the gap between the two ends of the spring, the size of the rigidity of the spring and the height of the spring can not be changed is solved, the three factors and the height of the spring under a given load form a one-to-one corresponding relation, and the accuracy of a test result is improved.
