Sole abrasion resistance testing device capable of simulating various environments

Abstract

A sole abrasion resistance testing device capable of simulating various environments comprises an experiment table base; two friction experiment devices are arranged at the front end of the experiment table base and mounted at an interval; driving motors used for controlling the movement of the experiment table base, couplers and torque sensors are mounted at two ends of the experiment table base respectively; a hydraulic pressurizing device is mounted in the middle of the experiment table base; a foot model device is connected to the output end of the hydraulic pressurizing device and arranged at the tops of the friction experiment devices. Due to up-down movement of transmission rollers in the friction experiment devices, discontinuous friction of two friction tapes on a shoe, gap between the friction tapes, and replaceability of the friction tapes, the front and back soles of the shoe are abraded by the two friction experiment devices respectively; due to the pressure control of the hydraulic stress application device, and replaceability of a foot model, the walking rules of people can be well simulated; due to torque change measurement of the torque sensors, change of friction coefficient can be obtained indirectly to reflect abrasion degree, so that the obtained data are more direct and accurate.

Description

technical field [0001] The invention relates to the technical field of friction testing mechanical equipment, in particular to a shoe sole wear resistance testing device that can simulate various environments, and can be used to test the wear resistance of shoe soles under various different conditions. Background technique [0002] At present, promoting a two-oriented society, saving resources and protecting the environment are the current priorities. Inappropriate design and selection of sole materials by shoe factories in the shoe production process will easily lead to increased wear of the soles, resulting in the scrapping of shoes, resulting in a great waste of sole material resources. pollute. The aspect of shoe sole performance evaluation can help to solve this problem. Elicit this project or test method. [0003] In the prior art, there are mainly the following deficiencies in the testing device for the wear resistance of the sole: [0004] One is that the test pr...

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 heel and forefoot. It is difficult to simulate the state of people walking and the different degrees of wear on the shoe in different environments, so the obtained sole is wear-resistant. Performance often does not match reality;

[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;

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

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