Description

Sneaker sole tolerance test device Technical Field The utility model relates to the field of sole detection equipment, in particular to a device for testing the tolerance of soles of sports shoes. Background The construction of the sole is quite complex and, in a broad sense, may include all of the materials comprising the sole, midsole, heel, etc. The sole is required to maintain wear resistance, impact resistance and slip resistance under high strength, multi-directional dynamic loads after production. The traditional sole quality detection technology has the following limitations: 1. In a single test mode, the conventional equipment mostly adopts an independent test unit, such as a vertical press machine, only evaluates static bearing capacity, a friction test table only measures unidirectional sliding resistance, and the sole can not bear composite stress of extrusion, shearing and rebound in the motion process. 2. Static simulation distortion conventional fatigue testing machines test the durability of the sole by means of mechanical bending at a fixed frequency, but ignore dynamic changes in the impact force when the foot is landed in actual motion (e.g., staged load differences of forefoot landing-heel off during running). 3. The problem of data fracture is that the pressure, friction coefficient and deformation recovery data output by different test equipment are mutually independent, and the synchronous correlation analysis is lacking, so that the comprehensive performance (such as the influence of rebound damping on the skid resistance) of the sole cannot be accurately estimated. 4. The ground suitability is insufficient, the traditional friction test adopts a panel made of fixed materials, and different road textures (such as runway grain lines and rainy ground tile lines) cannot be switched rapidly, so that the test result has deviation from the actual use environment. Therefore, an integrated testing device capable of synchronously simulating dynamic extrusion, multidirectional friction and rebound response is needed to solve the quality evaluation problem of the soles of the sports shoes under the complex working condition.
