Dynamic compression testing machine for midsole material of sports shoes

XJ818CDynamic compression testing machine for midsole material of sports shoes

The dynamic compression testing of midsole materials in sports shoes is a key method for evaluating their mechanical properties under high strain rates (such as running, jumping, and other rapid impacts). It mainly simulates sudden impact scenarios and tests the stiffness, energy absorption characteristics, and other properties of the materials. Provide reliable basis for product improvement and selection. From running to basketball shoes, from new material testing to durability evaluation, we comprehensively ensure sports safety and performance.

Interpretation of performance indicators:

Rebound rate: in the dynamic test, the material's ability to recover deformation after absorbing energy, for example, the rebound value of ETPU foam can reach 60%, and that of EVA can reach 50 – 55% after modification

XJ818CDynamic compression testing machine for midsole material of sports shoesRelated standards:

ASTM F1976 standard execution, using a universal material testing machine for compression set testing and dynamic compression testing of midsole materials. Biomechanics simulation testing utilizes biomimetic testing devices to simulate landing actions at different speeds, combined with high-speed camera systems to analyze the deformation process of the shoe body. The pressure distribution test uses insole or platform pressure measurement systems to collect plantar pressure data in accordance with ISO 20344 standard requirements. In addition, mechanical repeated impact equipment is used for long-term fatigue testing to evaluate the durability of shock absorption performance. All tests were conducted under standard temperature and humidity conditions, and sufficient sample sizes were collected to ensure the reliability of the data.
