A device for testing the abrasion resistance of shoe soles and its application

Abstract

The invention discloses a sole abrasion resistance testing apparatus and application thereof and belongs to the field of detection equipment. The sole abrasion resistance testing apparatus comprises a test bench base, the front end of the test bench base is provided with two friction testing device sets mounted in a spaced manner, two ends of the test bench base are fitted respectively with a drive motor for driving the base in motion, a coupling and a torque sensor; an adjustable-height support is mounted on the test bench base, a foot simulator is mounted on the support, hydraulic telescopic rod and elastic device output ends of the foot simulator are connected with a foot model device, and the foot model device is positioned at the top of the friction testing device. Complex motion of a foot in walking is divided into three sections by using leverage to simulate law of motion for a foot of a human in walking, changes in friction coefficient are acquired indirectly by using the torque sensor to measure changes in torque, and therefore acquired data are more direct and accurate.

Description

technical field [0001] The invention relates to a device for testing the wear resistance of shoe soles and its application, in particular to a device for testing the wear resistance of shoe soles in various simulated wearing environments by using the principle of leverage, which belongs to the field of testing equipment. Background technique [0002] At present, saving resources and protecting the environment is the current social development trend. Shoe manufacturers choose inappropriate sole materials in the shoe production process, which will easily increase the wear of the soles and shorten the service time of the shoes, resulting in a great waste of material resources. At the same time, discarded shoes are not easy to decompose and recycle, and are easy to pollute the environment. The evaluation of the wear resistance of the soles can help to solve this problem. [0003] In the prior art, there are mainly the following deficiencies in the testing device for the wear re...

AI Technical Summary

Problems solved by technology

[0004] One is that the test process only continuously rubs the sole on the friction plate, and cannot better measure the forefoot and heel of the shoe separately. It is difficult to simulate the state of a person walking and the characterization of the wear degree of the shoe on different ground environments. Moreover, the part where the worn sole is relatively limited in actual walking, so the wear resistance of the obtained sole is often significantly different from that of normal walking, which is inconsistent with the actual situation;

[0005] The second is that it is limited to testing two (or even more) shoes at the same time for each test, which leads to a slightly bulky size of the equipment, and it is difficult to judge the degree of wear of the sole when testing multiple groups of test products;

[0006] The third is that some equipment adopts the technology of mechanical feet, the structure of the device is complex, the stability and durability are poor, and the price is too expensive;

[0007] Fourth, there is no equipment that can easily measure the friction coefficient of finished shoes directly by installing them on the testing machine.
