Torsion testing machine BV series

torquefatiguePC-controllable

Product overview
Designed for combined axial and torsional loading, the BV series delivers comprehensive mechanical characterization of materials and components. Available in a wide range of load capacities, with torque up to 230 Nm, these axial-torsion systems combine a compact, rigid layout with the flexibility to integrate a full range of actuators (EA and UD).

Features

• Max. Torque: 230 Nm
• Control of two or more synchronised electromechanical axes
• Integrated absolute rotary encoder
• High-resolution 24-bit data acquisition
• Remote control capability
• Separate, independent control station
• Graphical Test Center interface for simple, flexible test management
• Wide range of grips, dedicated accessories and load cells
• Integration with strain gauges and climatic chambers

Test types

• Axial-Torsion (combined)
• Static
• Dynamic (including torsional fatigue and combined-load fatigue)

Applications

• Materials testing (metals, plastics, polymers — torsional fatigue and failure analysis)
• Biomedical (implants, bone and soft tissue mechanical characterisation, surgical instrument testing, implants/wires/screws)
• Automotive (driveshafts, rubber components, fasteners, suspension parts — fatigue testing)
• Aerospace (composite materials, structural components, combined-load fatigue analysis)
