Versatile Tire and Rubber Testing Systems

Bose offers a variety of test instruments to support research and development of tire and rubber products.

Bose’s tire and rubber testing instruments are highly versatile, and each system has a range of capabilities that are similar to having a number of testing systems integrated into a single unit.

Dynamic Mechanical Analysis (DMA) Testing

DMA analysis is performed for the following parameters:

• E*, E’, E”, tan δ
• Time-temperature superposition
• Feed modeling predictions: Wet traction and rolling resistance

Burst/Blowout Testing

Burst/blowout testing of tires (Figure 1) is done according to the following standards:

• Speed rating (prevents fatigue and heat build-up)
• Dynamic fatigue
• ASTM D623-07

Fatigue Testing

Fatigue testing methods are as follows:

• Flex (bend) testing (de Mattia - ASTM D430)
• Crack growth (bend) testing (de Mattia - ASTM D813)
• Crack growth modeling (tensile - ASTM D4482): Pulse waveform, Real-time strain control for elongating specimens, Relaxation compensation to account for specimen creep
• Dynamic stiffness/modulus degradation
• Speed rating characterization

Environmental Control Testing

Environmental control testing includes:

• Temperature and humidity control (portable version of system can be placed within temperature-humidity conditioner)
• Heating/cooling

General Testing

General testing methods are as follows:

• Creep (ISO 8013, ISO 2285)
• Compression (ASTM D395, D575; ISO 815)
• Tensile (ASTM D412; ISO 37)
• Stress relaxation (ASTM D6147; ISO 3384; ISO 2285)

Advanced/Other Testing

Other testing methods include:

• Multi-specimen testing
• Tire cord testing (ASTM D2285)
• Fast strain rate for studying strain-induced crystallization (dual motor specimen centering for in-situ monitoring)
• User-definable test protocols with conditional and logic testing
• Configurations may comprise torsion, bi-axial, multi-axial, and the likes

Friction-free Moving-Magnet Linear Motors

Friction-free moving-magnet linear motors from Bose deliver excellent performance across a wide range of displacement and force and can be used for performing the following tests:

• DMA
• Compression testing
• Monotonic tensile testing
• Stress-relaxation testing
• Creep testing
• High-cycle fatigue and durability testing
• Multi-axis and multi-sample testing
• Custom materials and component testing

Conclusion

Bose offers a wide range of testing instruments that are highly versatile and provide a suitable solution for various application needs. Bose’s testing solutions can be used in medical devices, engineered materials and biomaterials applications.
