Shoe Shank Stiffness Tester

Standard

SATRA TM256: Flexural and torsional stiffness testing for athletic, safety, and casual footwear.

SATRA TM194: Dynamic fatigue resistance evaluation for shoe midsole and outsole integrity.

Product Advantages

1. Dual-Mode Testing

Longitudinal & Torsional Stiffness: Simultaneously measures bending resistance (flex) and twist rigidity in a single cycle.

Universal Compatibility: Adapts to all shoe types—running, hiking, work, and orthopedic footwear.

2. High-Speed Automation

30 Cycles/Minute: Industrial-grade motor for rapid fatigue testing (0–50° flex angle).

Zero-Drift Actuators: Maintains ±0.1° angular accuracy over 100.000 cycles.

3. Precision Sensing

Strain Gauge Technology: 0.01 N·m resolution for torque and 0.1° angular feedback.

Self-Compensating Algorithms: Corrects for specimen slippage and hysteresis.

4. User-Centric Workflow

7” Touchscreen HMI: Pre-loaded SATRA protocols with adjustable test parameters.

Real-Time Curve Tracing: Live plots of torque vs. angle during testing.

5. Advanced Data Management

USB/PC Connectivity: Export raw data, cycles-to-failure, and stiffness coefficients.

Cloud Integration: Wireless sync to LIMS platforms for collaborative R&D.
