Bending testing machine PBFT-BP30

tensilefatiguecomputer-controlled

Product introduction
The PBFT-BP30 is a laboratory tester designed for bending and tensile fatigue testing of surgical implants, metal bone plates, bone screws and other orthopedic medical materials. It supports standardized test procedures and research on mechanical fatigue behaviour of implantable components.

Function

• Execute bending fatigue tests and tensile fatigue tests on surgical implants and metal bone plates.
• Acquire synchronized force/displacement data for durability and lifecycle analysis.
• Support custom test waveforms and programmable test sequences for R&D and validation.

Equipment description

• Measurement and control system composed of dynamic test host, dynamic fatigue loading module, specimen fixtures and PC-based control system.
• Two-column frame with electrically adjustable middle beam; actuator mounted at mid-crossbeam; sample mounted via dedicated fixtures on T-slots or pin-hole connector.
• Workbench with T-slots and central pin-hole connector to accommodate different fixtures and test configurations.
• High-precision actuator paired with an imported force sensor for accurate closed-loop control and reliable test data.
• Beam lifting mechanism driven by servo motor, synchronous belt and ball screw; manual controller available for fine adjustment; high-strength bolt locking with specified tightening torque.
• Fixture options: custom fixtures manufactured to standard requirements and installed on pin-hole connector or T-slot.
• Test execution supports sine and user-defined waveforms, adjustable frequency and amplitude, and synchronous data collection and storage.

Fatigue loading control software

• PCBP-system full digital closed-loop servo control integrating load sensor, displacement sensor, servo actuator and digital control software.
• Windows-based test software with simple operation, real-time process curve display, data processing, storage and export functions.
• Supported waveforms: sine, half-sine, triangular, square, oblique and combined waves; programmable control and automatic saving of key results (load, frequency, cycles, test time).
