Abstract

The article is devoted to the development of an express method for assessing the form stability of the heel of a shoe, which makes it possible to eliminate the existing shortcomings of the assessment method according to GOST 9135-2004 "Shoes. Method for determining the total and permanent deformation of the toe and heel".

The proposed method for rapid assessment of the form stability of the shoe toe and heel allows to quickly and reliably evaluate this indicator both during the production and the use products, as well as to study the dependence of the deformation of the heel of various shoe models on the load value. Comparative studies of the form stability of the heel of the shoe according to the developed methods and GOST 9135-2004 have shown the coincidence of the test results and the adoption of the hypothesis of equality of variances. When testing the static dimensional stability of the shoe heel according to the new methods, no shortcomings inherent in the method described in GOST 9135-2004 were revealed. That is, we can conclude that the values obtained by the developed methods are more objective. This allows us to state that their use for testing the dimensional stability of the heel of a shoe is more expedient.

The object of research is samples of men's, women's and children's shoes for the autumn-spring and summer seasons.

Results of the work are an express method and a device for assessing the form stability of the shoe heel.

The field of application of the results is the shoe industry.

The scientific novelty of the work lies in the fact that the proposed express method and device for assessing the form stability of the shoe heel allows to quickly and reliably evaluate this indicator both in production and during the use of the products, as well as to study the dependence of the deformation of the heel of various shoe models on the magnitude of the loading.
